Environmental analysis shows invest 90B is in a marginal environment for development, with weak radial outflow aloft, moderate 15-20 knot wind shear…offset by warm sea surface temperatures, Global models are in general agreement that invest 90B will not significantly intensify and will remain below tropical storm strength while tracking north-northeastward. Maximum sustained surface winds are estimated at 15-20 knots. The potential for the development of a significant tropical cyclone within the next 24 hours remains low.   https://www.nrlmry.navy.mil/htdocs_dyn_apache/PUBLIC/tc_pages/thumbs/medium/tc21/SHEM/90S.INVEST/ir/geo/1km_bw/20210402.140000.SH902021.ahi.himawari-8.Infrared-Gray.20kts.100p0.1p0.jpg There’s a second tropical disturbance being referred to as Invest 90S, which is located approximately 144 NM west-northwest of Christmas Island Here’s was the computer models are showing According to the JTWC, satellite imagery shows low-level banding wrapping into an elongated low-level circulation center that has moved southeastward over the past 12 hours. 90S is located in a favorable environment for development, characterized by low wind shear of 5-10 knots, warm sea surface temperatures, and ambient mid-level moisture. Dynamical models generally expect some consolidation of the system in the 48-72 hour range, as it tracks southeastward. Maximum sustained surface winds are estimated at 20 knots. The potential for the development of a significant tropical cyclone within the next 24 hours is low.   https://www.nrlmry.navy.mil/htdocs_dyn_apache/PUBLIC/tc_pages/thumbs/medium/tc21/SHEM/99S.INVEST/ir/geo/1km_bw/20210402.141000.SH992021.ahi.himawari-8.Infrared-Gray.25kts.100p0.1p0.jpg There’s a third tropical disturbance being referred to as Invest 99S, which is located approximately 75 NM west of Rote Island, Indonesia Here’s was the computer models are showing According to the JTWC, satellite imagery shows an elongated low-level circulation becoming better organized between a belt of 20-25 knot easterlies in the Timor sea and a belt of 30-35 knot westerlies north of the Savu Sea. Deep convection is patchy and decentralized, although formative curved banding is becoming apparent in the southern, western, and northern semicircles. 99S is embedded in a favorable environment with light northerly wind shear of 10 knots, warm sea surface temperatures…and deep-layer moisture. Dynamical models support continued consolidation of the broad circulation into a tropical cyclone south of Timor-leste in 24-48 hours. Maximum sustained surface winds are estimated at 25 knots. The potential for the development of a significant tropical cyclone within the next 24 hours is medium.   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!
