Forum:2019 Pacific typhoon season/September

September
Added this section already, especially given the fact that there are two JMA TDs and one invest which might form in September that are currently being monitored in the WPac. Anonymous 2.0 (talk) 13:42, August 31, 2019 (UTC)

93W.INVEST
Another invest on Tropical Tidbits, located out in the open Pacific. This basin really is on fire. ~  Steve   Talk Page  My Edits  📧  00:11, September 2, 2019 (UTC)
 * Still a low on JMA. Anonymous 2.0 (talk) 09:54, September 2, 2019 (UTC)

JMA Tropical Depression (93W.INVEST)
JMA has upped this to a depression and it's located to the east of the Philippines. Likely to become Peipah (assuming 14W becomes Faxai) and Marilyn. ~  Steve   Talk Page  My Edits  📧  21:32, September 4, 2019 (UTC)

Remnants of JMA Tropical Depression (93W)
Or maybe not. JMA has downgraded this to a low, but there's plenty of sea ahead of it, so it's never too late, I guess? Jas (Anonymous 2.0) (talk) 17:14, September 5, 2019 (UTC)
 * No longer on Tropical Tidbits. Look at 95W for development. ~  Steve   Talk Page  My Edits  📧  20:14, September 6, 2019 (UTC)

JMA Tropical Depression (SCS between 91W & the Philippines)
Apparently JMA has upgraded this to a TD. Still not present in JTWC's page though. Anonymous 2.0 (talk) 04:31, September 2, 2019 (UTC)

Scratch that. This is actually at the South China Sea. May be absorbed by 91W though, as the latter system is actually forecast to move eastward after making a turn near Hainan. Anonymous 2.0 (talk) 09:54, September 2, 2019 (UTC)

JMA Tropical Depression (94W.INVEST)
It's actually been invested and added to JTWC's page with a code red (TCFA issued). A bit strange how it's developing so close to Kajiki, they almost seem like one single system due to the monsoon's influence. ~  Steve   Talk Page  My Edits  📧  01:05, September 3, 2019 (UTC)
 * No longer on JMA's weather map, but still code red on JTWC. Seems that Kajiki will either merge with this one or completely absorb it. Anonymous 2.0 (talk) 12:01, September 3, 2019 (UTC)

Remnants of JMA Tropical Depression (94W.INVEST)
Looks like this is dying out or merging with Kajiki. TCFA cancelled. ~  Steve   Talk Page  My Edits  📧  23:00, September 3, 2019 (UTC)

95W.INVEST
New invest in the middle of the Pacific. Code yellow as of the moment. Jas (Anonymous 2.0) (talk) 13:10, September 6, 2019 (UTC)
 * A candidate for Peipah. Hopefully it'll be a fishspinner. ~  Steve   Talk Page  My Edits  📧  20:12, September 6, 2019 (UTC)
 * Upped to code orange. More likely than 96W to become Peipah tbh. ~  Steve   Talk Page  My Edits  📧  03:52, September 9, 2019 (UTC)
 * May not become a fishspinner though. Weather models still do not have a consensus on this one. Still code orange on JTWC. Jas (Anonymous 2.0) (talk) 07:20, September 10, 2019 (UTC)

JMA Tropical Depression (95W.INVEST)
Finally upgraded by JMA to a TD. Expected to be named Marilyn by PAGASA once this enters their jurisdiction. Jas (Anonymous 2.0) (talk) 10:55, September 10, 2019 (UTC)

JMA Tropical Depression (95W/Marilyn)
Named by PAGASA as it enters their area of responsibility. ~  Steve 😔   9/11  Never forget. 🙏  AMERICA IS STRONG! 🗽🇺🇸  06:41, September 12, 2019 (UTC)
 * Code red, TCFA issued on JTWC. ~  Steve   Talk Page  My Edits  📧  15:39, September 13, 2019 (UTC)

Tropical Depression Marilyn (95W)
Downgraded to a low on JMA. PAGASA's still issuing advisories though. ~  Steve   Talk Page  My Edits  📧  21:08, September 13, 2019 (UTC)

Remnants of Marilyn (95W)
PAGASA has issued their last advisory. Still code red on JTWC but they might downgrade it soon. ~  Steve   Talk Page  My Edits  📧  15:20, September 14, 2019 (UTC)
 * Still code red, TCFA still on. Currently considered by JTWC as a monsoon depression. Jas (Anonymous 2.0) (talk) 05:42, September 15, 2019 (UTC)
 * Back down to code yellow. ~  Steve   Talk Page  My Edits  📧  06:24, September 15, 2019 (UTC)
 * Still code yellow. Recognized by PAGASA as a distinct system, but JTWC considers this as 95W. Might be renamed as Nimfa. Jas (Anonymous 2.0) (talk) 13:56, September 16, 2019 (UTC)

JMA Tropical Depression (Ex-Marilyn/95W)
This appears to have regenerated into a tropical depression according to JMA's weather map. ~  Steve   Talk Page  My Edits  📧  03:13, September 17, 2019 (UTC)

JMA Tropical Depression (Marilyn-Nimfa/95W)
Code orange now, but PAGASA and JMA treat this as a separate system which formed from the remnants of Marilyn. Jas (Anonymous 2.0) (talk) 10:03, September 17, 2019 (UTC)
 * A bit strange how the PAGASA gives a system a new name if it regenerates instead of continuing with the old name like the NHC does. Upped to code orange on JTWC, and model guidance and forecasts are getting more bullish with this system on its approach to Japan and Korea. ~  Steve   Talk Page  My Edits  📧  18:43, September 17, 2019 (UTC)
 * Now code red on JTWC, TCFA issued. ~  Steve   Talk Page  My Edits  📧  15:56, September 18, 2019 (UTC)

Tropical Depression 18W (Nimfa)
The JTWC has began advisories on 18W. JMA currently has it as a 35 mph (10-min)/998 mbar depression, while it's only a measly 30 mph (1-min) on JTWC. I expect this to become "Tapah". ~  Steve   Talk Page  My Edits  📧  03:58, September 19, 2019 (UTC)

Tropical Storm Tapah (Nimfa)
And so it becomes Tapah. Still a TD on JTWC though. Jas (Anonymous 2.0) (talk) 08:13, September 19, 2019 (UTC)
 * Now a TS on JTWC, expected to peak as a severe tropical storm but might have a chance at typhoon strength. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  15:43, September 19, 2019 (UTC)
 * Upped to 45 mph (1 and 10-min)/990 mbar. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  00:52, September 20, 2019 (UTC)

Severe Tropical Storm Tapah (Nimfa)
Now a severe tropical storm. 65 mph (10-min) and 60 mph (1-min)/975 mbar. Still a good possibility that it becomes a minimal typhoon. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  18:25, September 20, 2019 (UTC)
 * Closing in on typhoon strength. Now 70 mph (JMA 10-min) and 65 mph (JTWC 1-min). ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  21:22, September 20, 2019 (UTC)

Typhoon Tapah (Nimfa)
It has intensified to a typhoon according to JMA (75 mph/970 mbar). JTWC keeps it at strong tropical storm intensity for now. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  00:54, September 21, 2019 (UTC)

Severe Tropical Storm Tapah (Nimfa) (2nd time)
Back down to a STS, 70 mph/975 mbar according to JMA as it moves into Korea/Japan territory and has exited PAGASA's region (probably a while ago). Never has been considered a typhoon by JTWC as far as I know. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  03:14, September 22, 2019 (UTC)
 * The center is now moving along Japan's west coast and it's down to 65 mph/985 mbar. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  19:01, September 22, 2019 (UTC)
 * Even if it is kinda unreliable, Wikipedia said that Tapah briefly became a C1. Anyway, this will dissipate soon, it was fun (but also daunting) to track. Jas (Anonymous 2.0) (talk) 19:39, September 22, 2019 (UTC)

Remnants of Tapah (Nimfa)
Downgraded to a low per JMA and the final advisories have been issued. Wikipedia's page actually says it peaked as a tropical storm per JTWC, I guess the earlier revision you saw was a mistake. I don't remember any time that JTWC had it at typhoon intensity. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  01:55, September 23, 2019 (UTC)
 * Maybe it was a glitch or some error by an editor. So far, Tapah only had minor impacts, and I hope it stays that way especially now that another typhoon is threatening east Asia (that is, of course, Mitag). Jas (Anonymous 2.0) (talk) 22:55, September 29, 2019 (UTC)

JMA Tropical Depression (96W.INVEST)
A wild depression has popped up near Taiwan. Already invested but not on JTWC's outlook yet. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  06:01, September 7, 2019 (UTC)
 * Now code yellow on JTWC. I don't think this would be anything, as it seems to follow Lingling's [cold] wake. Jas (Anonymous 2.0) (talk) 07:29, September 7, 2019 (UTC)
 * I don't really see much coming out of this either, but there's still a chance it could steal "Peipah" (hopefully not). Now code orange on JTWC. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  03:53, September 9, 2019 (UTC)
 * This system was actually considered as a subtropical depression by JTWC, though it has been dropped from their weather map now. Jas (Anonymous 2.0) (talk) 07:18, September 10, 2019 (UTC)

Remnants of JMA Tropical Depression (96W.INVEST)
It's dying out now, no longer a TD on JMA's weather map. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  01:58, September 11, 2019 (UTC)

97W.INVEST
Up on Tropical Tidbits all the way out near the Marshall Islands. ~ <font face="Impact"> Steve 😔   9/11  Never forget. 🙏  AMERICA IS STRONG! 🗽🇺🇸  06:29, September 11, 2019 (UTC)

JMA Tropical Depression (97W.INVEST)
Upgraded to a TD on JMA's weather map. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  03:25, September 13, 2019 (UTC)
 * Code yellow on JTWC, along with 98W. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  06:38, September 13, 2019 (UTC)
 * Now code orange. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  15:38, September 13, 2019 (UTC)

Tropical Depression 17W
Expected to remain as a TD, according to JTWC. Jas (Anonymous 2.0) (talk) 05:42, September 15, 2019 (UTC)

Tropical Storm Peipah
It stole Peipah...sigh. Not expected to surpass it's current intensity. What an epic failure. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  15:24, September 15, 2019 (UTC)

Tropical Depression Peipah
Downgraded to a TD on JMA and final warning issued by JTWC, should dissipate pretty soon. What a steal of a name. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  01:09, September 17, 2019 (UTC)

Remnants of Peipah
And it's dead. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  03:11, September 17, 2019 (UTC)

98W.INVEST
Another on Tidbits, located just to the northwest of 95W/TD Marilyn. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  15:28, September 12, 2019 (UTC)
 * Now code yellow on JTWC, along with 97W. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  06:39, September 13, 2019 (UTC)

JMA Tropical Depression (98W)
Now a TD per JMA. Weirdly, their weather map shows that ex-95W/Marilyn has a lower pressure (998 mb) than this one and 17W. Still code yellow on JTWC though. This is actually at Marilyn's northeast. Jas (Anonymous 2.0) (talk) 05:45, September 15, 2019 (UTC)

Remnants of JMA Tropical Depression (98W)
Downgraded to a low on JMA, no longer on JTWC. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  06:43, September 16, 2019 (UTC)

JMA Tropical Depression (99W)
TD on JMA, code yellow on JTWC. This is at the west of Luzon. Jas (Anonymous 2.0) (talk) 10:04, September 17, 2019 (UTC)

Remnants of JMA Tropical Depression (99W)
No longer on JMA's map, but still code yellow on JTWC. It has also made landfall in Luzon I think. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  03:49, September 18, 2019 (UTC)
 * No longer on JTWC's outlook. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  06:48, September 18, 2019 (UTC)

90W.INVEST
Another one on Tidbits located way out to sea, east of Guam. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  15:59, September 18, 2019 (UTC)
 * Long dead. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  18:35, September 25, 2019 (UTC)

JMA Tropical Depression (91W)
Up on JTWC with code yellow, and up as a TD on JMA's weather map with a 1010 mbar pressure. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  18:35, September 25, 2019 (UTC)
 * Intensified to 1008 mbar. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  21:12, September 25, 2019 (UTC)
 * Now code orange on JTWC. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  00:17, September 26, 2019 (UTC)
 * Back down to 1010 mbar on JMA's weather map. I'm still hoping for Mitag out of this. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  03:33, September 26, 2019 (UTC)
 * Code red, TCFA issued. JMA has begun advisories on their front page, it's currently 35 mph/1010 mbar. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  15:23, September 26, 2019 (UTC)
 * Back up to 1008 mbar, still 35 mph on JMA. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  18:30, September 26, 2019 (UTC)

Tropical Depression 19W
And JTWC follows suit. Widely expected to become Mitag and may hit Taiwan and Japan in the long run. Jas (Anonymous 2.0) (talk) 12:41, September 27, 2019 (UTC)
 * Intensified to 1006 mbar according to JMA, currently 35 mph according to both agencies. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  15:34, September 27, 2019 (UTC)
 * JMA keeps it as a 35 mph/1006 mbar tropical depression for now, but JTWC has upped it to a tropical storm with 40 mph winds. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  21:54, September 27, 2019 (UTC)

Tropical Storm Mitag (Onyok)
Now a tropical storm according to both JMA and JTWC. It has also entered PAGASA’s AOR, getting the name Onyok. JTWC expects this system to become a low-end C3 as its peak.  Sandy 156   :)  06:13, September 28, 2019 (UTC)
 * Currently 40 mph/1000 mbar according to JMA and 45 mph according to JTWC. I don't really like the looks of this system threatening land as a powerful typhoon in the long run. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  06:49, September 28, 2019 (UTC)
 * Latest updates: still a TS by JMA (50 mph/996 mbar), but up to 60 mph on JTWC. JMA should upgrade it to a STS very soon. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  18:15, September 28, 2019 (UTC)

Severe Tropical Storm Mitag (Onyok)
Now a STS, 60 mph/992 mbar according to JMA. Forecast peak is now 75-80 knots (85-90 mph). ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  00:43, September 29, 2019 (UTC)
 * Almost a typhoon... 70 mph/980 mbar according to JMA. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  06:47, September 29, 2019 (UTC)

Typhoon Mitag (Onyok)
Now a typhoon, 75 mph/975 mbar. Still expected to peak around 85-90 mph, and now Taiwan, China, and South Korea are in the line of fire. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  19:56, September 29, 2019 (UTC)
 * Mitag is a C2 now: 100 mph (85 kn), 970 hPa. Forecast to come very close to eastern China before turning northeast towards Japan and the Koreas. Jas (Anonymous 2.0) (talk) 17:45, September 30, 2019 (UTC)
 * JTWC currently has it as a 105 mph C2 but JMA has it only at 85 mph. Pressure has decreased further to 965 mbar. It appears to be close enough to China to cause impacts and hopefully South Korea and Japan won't get hit too badly. ~ <font face="Impact"> Steve   Talk Page  My Edits  📧  00:50, October 1, 2019 (UTC)

Severe Tropical Storm Mitag (Onyok) (2nd time)
Down to 70 mph/980 mbar. Looks like strong shear and interaction with China might have weakened it. Expected to begin extratropical transition as it crosses through South Korea and Japan. ~ <font face="Verdana"> Steve   Message Me  My Edits  📧  18:33, October 1, 2019 (UTC)
 * Continues to weaken - 65 mph (JTWC), 60 mph (JMA)/985 mbar as it approaches South Korea. ~ <font face="Verdana"> Steve   Message Me  My Edits  📧  03:25, October 2, 2019 (UTC)

Tropical Storm Mitag (Onyok) (2nd time)
Down to a TS, 50 mph (JMA), 45 mph (JTWC)/990 mbar. ~ <font face="Verdana"> Steve   Message Me  My Edits  📧  15:32, October 2, 2019 (UTC)

Landfall in South Korea
Made landfall and is down to 45 mph (both agencies)/994 mbar. ~ <font face="Verdana"> Steve   Message Me  My Edits  📧  19:36, October 2, 2019 (UTC)

Remnants of Mitag (Onyok)
And now it's dead, after causing impacts to Taiwan, China, Korea, parts of Japan and maybe parts of the Philippines. The tropics are now dormant for the time being. ~ <font face="Verdana"> Steve   Message Me  My Edits  📧  15:14, October 3, 2019 (UTC)
