Unexpectedly, one invest on the Southwestern Indian Ocean just formed. It's at a low chance of formation according to JTWC. I doubt this would form. Hi!-68.106.0.77 02:49, August 9, 2017 (UTC)

 * Saw this a couple days ago on JTWC and was a bit surprised to see something being monitored down there during their winter. ~  Steve   Talk Page  My Edits  📧  05:03, August 12, 2017 (UTC)

Don't think many will read this, but we have another unusual early-season invest here in the SWIO. The JTWC is monitoring it with a low chance of development. ~  Steve   Talk Page  My Edits  📧  04:41, September 9, 2017 (UTC)


 * And another one... Hurricanes, hurricanes, hurricanes!-68.106.0.77 03:57, September 11, 2017 (UTC)

Here to report that another pre-season invest has formed west of the Seychelles. And it's up on JTWC with code yellow (low chance of developing). ~  Steve   Talk Page  My Edits  📧  03:20, September 28, 2017 (UTC)


 * Ok, the pre-season invests are getting annoying now. Hurricanes, hurricanes, hurricanes! -68.106.0.77 14:32, September 28, 2017 (UTC)


 * JTWC has now dropped it. ~  Steve   Talk Page  My Edits  📧  18:22, October 1, 2017 (UTC)

94S.INVEST
This was a short-lived invest that I remember seeing on Tropical Tidbits a couple days ago. It's dead now. The SHem should start ramping up soon. ~  Steve   Talk Page  My Edits  📧  19:58, November 18, 2017 (UTC)

99S.INVEST
North of Madagascar. No agency expects development, yet. ~  Steve   Talk Page  My Edits  📧  02:10, December 5, 2017 (UTC)


 * Now low risk on Meteo France. Still no mention on JTWC. Ava, anyone? ~  Steve   Talk Page  My Edits  📧  02:37, December 6, 2017 (UTC)
 * Off the Mateo France outlook and about to make landfall near the Tanzania-Mozambique border. This won't develop anymore. ~  Steve   Talk Page  My Edits  📧  02:35, December 9, 2017 (UTC)

90S.INVEST
A new invest just northeast of Madagascar. Low risk on Mateo France, and appears to have more Ava potential than 99S ever did. ~  Steve   Talk Page  My Edits  📧  02:35, December 9, 2017 (UTC)
 * Long dead... ~  Steve 🎅   Happy  Holidays!  🎄  21:37, December 26, 2017 (UTC)

94S.INVEST
New one out in open ocean, up on Tropical Tidbits and NRL. Medium risk on TCWC Reunion. Could this be Ava? ~  Steve 🎅   Happy  Holidays!  🎄  21:37, December 26, 2017 (UTC)
 * Up on JTWC with low chance, and high risk (code red) on TCWC Reunion. Here comes the season's first storm! ~  Steve 🎅   Happy  Holidays!  🎄  06:45, December 29, 2017 (UTC)

Zone of Disturbed Weather 01
25 mph/1006 mbar,should develop soon.JoeBillyBob (talk) 06:36, December 30, 2017 (UTC)


 * looks to have plenty of model support.JoeBillyBob (talk) 11:53, December 29, 2017 (UTC)
 * Now code orange on JTWC. TCWC Reunion appears to forecast a moderately strong cyclone heading towards northern Madagascar. ~  Steve   Goodbye  2017!  ⚰️  05:50, December 31, 2017 (UTC)

Moderate Tropical Storm Ava
Fresh from TCWC Reunion: it has been named "Ava". Expected to make landfall on the eastern Madagascar coast on the 5th, likely strengthening more along the way. ~  Steve 🎉   2018  is here!  🎆  06:50, January 3, 2018 (UTC)

Severe Tropical Storm Ava
That was fast.60 mph/987 mbars.123.243.135.221 09:38, January 4, 2018 (UTC)

Tropical Cyclone Ava
Continues to intensify, 85 mph (JTWC 1-min) and 80 mph (10-min)/970 mbars. Expected to run parallel to the eastern Madagascar coast, and any population centers along that coast could receive plenty of impacts. JTWC forecasts a strong cyclone moving parallel to the coast (not good for them) while TCWC Reunion forecasts it to move inland and become a remnant low, before regenerating off the coast of southeastern Madagascar. ~  Steve 🎉   2018  is here!  🎆  06:51, January 5, 2018 (UTC)

Overland Depression Ava
Been an overland depression for a while now, and is just now moving back out to sea. It has some reintensification potential as it moves southeast of Madagascar. Hopefully it wasn't too bad there. ~  Steve ❄   Talk Page  My Edits  📧  06:49, January 7, 2018 (UTC)

Moderate Tropical Storm Ava (2nd time)
Back to a MTS, but unlikely to intensify much. Its structure got shredded by Madagascar. ~ KN2731 {talk} 09:40, January 7, 2018 (UTC)

Remnants of Ava
Been dead for a couple days already. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  04:58, January 12, 2018 (UTC)

On the JTWC outlook with a high chance of forming. Hi!-70.190.21.73 17:51, January 5, 2018 (UTC)

Moderate Tropical Storm Irving
Actually, this has been named for at least a day now and has recently moved into this basin from the Australian region. Irving is expected to gradually intensify to about "Tropical Cyclone" intensity while staying out to sea. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  06:49, January 7, 2018 (UTC)

Severe Tropical Storm Irving
Uppped to STS, but JTWC already has this at C1 status. ~ KN2731 {talk} 09:38, January 7, 2018 (UTC)

Tropical Cyclone Irving
This was Irving's maximum intensity. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  05:03, January 12, 2018 (UTC)

Remnants of Irving
Dead since the 9th. I haven't really had time to update this due to college and real life. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  05:03, January 12, 2018 (UTC)

Zone of Disturbed Weather 02
High chance on JTWC and TCWC Reunion has declared it a "Zone of Disturbed Weather". It's currently out in open sea, but is likely to track towards Madagascar in the long run. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  05:03, January 12, 2018 (UTC)

Intense Tropical Cyclone Berguitta
This has become very intense and is now the equivalent to a major hurricane. It looks like a threat to Mauritius and Reunion. Also, this wiki has gone dead quiet. This will be my last post on this wiki until May, unless a surprise pops up. I'd rather not keep talking to myself. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  06:35, January 16, 2018 (UTC)


 * Berguitta just weakened to Category 2 status according to JTWC. Probably upwelling since it's been stationary for a couple of days already. Sorry for inactivity, I guess we're all busy (like me :/) or bored with this season's general SHEM inactivity... ~ KN2731 {talk} 11:27, January 16, 2018 (UTC)


 * I’ve been busy, but trying to post more. Also Berguitta is now a Category 1. Leeboy100 Hello!! 01:22, January 17, 2018 (UTC)

Tropical Cyclone Berguitta
Back down to just a TC, intensity is at 85 kt/963 mbar. This could be potentially devastating for Mauritius and Reunion. T G  2 0 1 8 16:16, January 16, 2018 (UTC)


 * Looks like Berguitta will hit the two islands in a day or two. Mauritius and Reunion are no stranger to tropical cyclones; in fact, the wettest tropical cyclones in the world have dropped enormous amounts of rainfall on the two islands, though the low intensity of this storm and it's forward speed should hopefully keep it from being too bad. Worst case is, this could stall like Gamede of 2007 or Hyancithe of 1980 and drop several feet of rain on the islands. But that aside, yeah, we usually don't pay as much attention to the SHem as we do the NHem, but sometimes activity kicks up here if a notable storm forms (like Winston).

Severe Tropical Storm Berguitta
I've noticed on my weather page on Instagram, many people were wondering if it would be like Hyacinthe or Firinga. Anyways, Berguitta is now at 80 kt/965 mbar (1-min sustained). 75 kt/965 mbar (10-min sustained). T G  2 0 1 8 13:26, January 17, 2018 (UTC)


 * Center just passed very close to Mauritius. La Reunion is next in the line of fire. ~ KN2731 {talk} 11:10, January 18, 2018 (UTC)


 * Berguitta just missed Reunion. Fortunately, Berguitta is not as bad as what the original forecast looked like. T  G  2 0 1 8 14:12, January 18, 2018 (UTC)
 * Currently the storm has caused at least 12 million in damage and at least 1 death. Hopefully it doesn't get much worse than that. Ryan1000 21:08, January 19, 2018 (UTC)

Moderate Tropical Storm Berguitta
Downgraded back to a moderate TS and expected to continue weakening from here on out. Sorry to hear the impacts. :( Also, I didn't expect to see all of you guys suddenly posting after my "last post until May"! As long as there's still some activity here, I guess I will continue posting through the NHem off-season. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  23:56, January 19, 2018 (UTC)

Remnants of Berguitta
Luckily, this storm has finally dissipated, and I hope that damage total and death toll stays the same. We do not need a destructive SWIO storm again. Ava was already enough when it caused 51 fatalities in Madagascar. T G  2 0 1 8 14:40, January 20, 2018 (UTC)

Tropical Depression 04
This was a short-lived TD that made landfall in northern Mozambique. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  06:35, January 16, 2018 (UTC)

Overland Depression 04
And it's dying already. ~ KN2731 {talk} 11:25, January 16, 2018 (UTC)

Tropical Disturbance 04
And it died off quickly. Hi!-70.190.21.73 14:25, January 17, 2018 (UTC)

Remnants of 04 (99S.INVEST)
It's actually back up on JTWC, with code yellow (low chance) as it appears to be moving back over water. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  23:58, January 19, 2018 (UTC)
 * Still at code yellow, but I think there could be a slight chance that it could become a weak Cebile before running back into Mozambique or Madagascar. I really hope this hasn't caused major flooding in that country, as it has been stalled over the same general area of Mozambique since January 15. T  G  2 0 1 8 14:42, January 20, 2018 (UTC)


 * I hope it wasn't too flooding either. This system has actually crossed Madagascar and is now entering the open Indian, where a chance of redevelopment could exist. I don't think I've ever heard of a storm make landfall in Mozambique and then move back out into the open Indian (not the Mozambique Channel, but everything east of Madagascar). Still code yellow per JTWC. ~ <font face="Impact"> Steve ❄   Talk Page  My Edits  📧  03:03, January 22, 2018 (UTC)


 * Code orange on jtwc.JoeBillyBob (talk) 07:01, January 24, 2018 (UTC)

 * Okay, first of all, THIS IS NOT EVEN A CLASSIFIED STORM. Secondly, if this were to be invested, it would be Invest 90S, not 91S. Please pay attention to JTWC before posting things that are not true. Sorry to come off sounding rude. T  G  2 0 1 8 21:32, January 24, 2018 (UTC)
