South Indian Ocean

Tropical Cyclone 10S
https://www.metoc.navy.mil/jtwc/products/10S_151200sair.jpg Here’s what the computer models are showing Sustained 35 knot winds…with gusts to 45 knots (as of Warning Number 1) According to the JTWC…satellite imagery reveals flaring deep convection obscuring a consolidating low level circulation. Analysis indicates a marginally favorable environment with low to moderate 10-20 knot wind shear, warm sea surface temperatures, and moderate poleward outflow aloft. TC 10S will steadily intensify to a peak of 50 knots by 48 hours, due to marginally favorable conditions. After 72 hours, the intensity will begin to decrease due to increasing wind shear, decreasing mid-level moisture, and convergent flow aloft.

Global models are in good agreement that invest 99S will track to the west-southwest as it slowly intensifies. Maximum sustained surface winds are estimated at 28-33 knots. The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to high.   https://www.nrlmry.navy.mil/htdocs_dyn_apache/PUBLIC/tc_pages/thumbs/medium/tc21/SHEM/91P.INVEST/ir/geo/1km_bw/20210116.053000.SH912021.ahi.himawari-8.Infrared-Gray.20kts.100p0.1p0.jpg There’s a second tropical disturbance being referred to as Invest 91P Here’s what the computer models are showing The potential for the development of a significant tropical cyclone within the next 24 hours is low.
