Global models are in good agreement that 90S will continue to track generally southeastward, remaining elongated while intensifying, potentially reaching warning threshold in 2-4 days. Maximum sustained surface winds are estimated at 20-25 knots. The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to medium.   https://www.nrlmry.navy.mil/htdocs_dyn_apache/PUBLIC/tc_pages/thumbs/medium/tc21/SHEM/99S.INVEST/ir/geo/1km_bw/20210403.140000.SH992021.ahi.himawari-8.Infrared-Gray.30kts.100p0.1p0.jpg There’s a second tropical disturbance being referred to as Invest 99S, which is located approximately 209 NM north of Browse Island, Australia. Here’s was the computer models are showing According to the JTWC, satellite imagery shows flaring deep convection circling a partially obscured low level circulation center with fragmented formative banding wrapping in from the south and east. 99S is currently in a favorable environment with warm sea surface temperatures, low 10 to 15 knot wind shear, and good radial outflow. Global models are in general agreement that 99S will remain largely quasi-stationary with slightly northeastward movement before turning 180 degrees to the southwest in around 18-24 hours. In that time, 99S will continue to intensify; however, models disagree on timing with the majority predicting 99S reaching warning threshold in approximately 36 hours, while ECMWF, the only outlier, predicts a quicker intensification, reaching warning threshold in 12 to 24 hours. Maximum sustained surface winds are estimated at 25-30 knots. The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to high.   Here’s a link to the Joint Typhoon Warning Center (JTWC)   For real-time information on current disasters download PDC’s free Disaster Alert mobile app available for your iOS or Android devices today!
