Moderate Tropical Storm Haleh
A new storm is born in the SWIO. This storm, named Haleh, is expected to move south-southwest over open water, but could become at least a category 2 (by the JTWC) before dissipating out to sea. Ryan1000 10:51, March 2, 2019 (UTC)

Severe Tropical Storm Haleh
Up to a STS. Ryan1000 20:01, March 3, 2019 (UTC)

Tropical Cyclone Haleh
Up to a category 3 by the JTWC. Ryan1000 12:29, March 4, 2019 (UTC)

Intense Tropical Cyclone Haleh
Now the record SIXTH intense tropical cyclone of the season! Wow, just wow. IbAHAn1829 \I like weather/ \Contributions/ 01:08, March 5, 2019 (UTC)

Tropical Cyclone Haleh (2nd time)
Weakening over water...Ryan1000 18:00, March 6, 2019 (UTC)

 * The JTWC is strangely still issuing advisories on this. IbAHAn1829 \I like weather/ \Contributions/ 00:01, March 9, 2019 (UTC)

They shouldn't be...it's practically over freezing South Indian Ocean waters at this point. It's no threat to land either. Ryan1000 04:08, March 11, 2019 (UTC)

Tropical Depression 11
A new depression is here, though this should be short-lived as it moves northwest into Mozambique. Ryan1000 13:58, March 4, 2019 (UTC)

Remnants of 11
Gone. Ryan1000 14:02, March 7, 2019 (UTC)
 * TCFA now on JTWC, 11 could be making a comeback. IbAHAn1829 \I like weather/ \Contributions/ 00:02, March 9, 2019 (UTC)

Tropical Depression 11 (2nd time)
TD 11 has now officially redeveloped by the JTWC, a TS in the SSHWS scale. It is now back in the Mozambique Channel.  Sandy 156   :)  18:32, March 9, 2019 (UTC)

Moderate Tropical Storm Idai
Now a tropical storm, and named Idai. I really don't like how this storm managed to reverse direction back over the Mozambique Channel; the current JTWC forecast not only has this storm recurving back west into Mozambique again but it also has this storm rapidly intensifying to at least a 125 mph category 3 storm before making landfall in Mozambique again as at least a 100 mph storm. This isn't good...if that intensity forecast ends up being conservative, and Idai gets stronger than that, then this could be one of Mozambique's worst tropical cyclones ever, alongside Eline in 2000. Ryan1000 02:42, March 10, 2019 (UTC)

Tropical Cyclone Idai
Already an 80 mph C1 per the JTWC. It is now forecast to peak (and possibly make landfall) at 140 mph. IbAHAn1829 \I like weather/ \Contributions/ 01:26, March 11, 2019 (UTC)


 * Idai could possibly intensify all the way to category 5 at the rate this thing is going, it's currently at 105/956 by the JTWC and 90/968 by MFR. Idai could lose some intensity just before making another landfall in Mozambique to the north of Beira, but it will likely still be a very formidable storm when it comes ashore, as at least a 120 mph storm according to the JTWC's latest forecast. The last category 3 storm to hit Mozambique was Jokwe in 2008, but that storm only skimmed along part of the coastline before moving southward into the Mozambique channel. Hopefully they can evacuate everyone in the storm's path. Ryan1000 04:06, March 11, 2019 (UTC)

Intense Tropical Cyclone Idai
Idai is now the record-breaking SEVENTH intense tropical cyclone of the season! JTWC has it at 115 mph at the moment, is forecasting a 145 mph peak intensity and a 95 mph landfall. Lets hope they stay at a below major hurricane intensity landfall, or else Mozambique is going to get trashed. IbAHAn1829 \I like weather/ \Contributions/ 12:39, March 11, 2019 (UTC)


 * Idai is at 105 mph and 960 mbars according to MFR, but TropicalTidbits actually says Idai is at 115 knots, or 130 mph, a category 4 on the SSS, and 937 mbars by the JTWC, and JTWC predicts a 95 knot (110 mph) landfall on Mozambique. Idai could weaken a little from upwelling over its own wake or some unfavorable conditions near shore, but if Idai picks up speed soon on its southwest, then northwest movement, then there's practically nothing that'll stop this from becoming a top-end cat 4 or cat 5 storm. Ryan1000 12:54, March 11, 2019 (UTC)

As a side note, if you check out the latest advisory from MFR, Idai is forecast to produce a storm surge of up to 6 meters (21 feet) if it is a category 4 at landfall. There is still uncertainty over how strong it'll be and where it'll hit, but the looping track of Idai in the long run is very worrisome, especially for flooding. Ryan1000 13:25, March 11, 2019 (UTC)

Tropical Cyclone Idai (2nd time)
Idai has been weakening over the past day due to a combination of an ERC and some upwelling over its own wake due to it's slow movement yesterday, but Idai appears to be trying to reform a much larger, more symetrical eye on sattelite imagery by now. If it reforms soon, then it could reintensify to a large and powerful category 3 or 4 storm before making landfall just north of Beira on Friday or Saturday. Hopefully the city has been or is being evacuated. Ryan1000 15:27, March 12, 2019 (UTC)


 * Back up to category 3 by the JTWC and forecast to reach category 4 again, and maintain 130 mph winds at landfall, which is now forecast to be a near direct hit on Beira (population of over 533,000 people). This isn't good...Ryan1000 00:03, March 13, 2019 (UTC)

...Where is everyone? We have an enormous tropical cyclone spiraling towards Mozambique as we speak. Idai's eye has lately become cloud-free and I see nothing stopping this storm from absolutely exploding before landfall in a day or two, easily back up to category 3 or 4 intensity and it could bring a storm surge up to 20 feet or more directly on the coast of Beira. Not to mention the eye of this thing is almost 40-50 miles wide at this point. This thing is starting to take on annular characteristics and will likely bring massive flooding to central Mozambique. It could easily be one of the worst TC's to affect the country on record. Ryan1000 18:04, March 13, 2019 (UTC)
