Tropical Cyclone 26S (Seroja)
Sustained 65 knot winds…with gusts to 80 knots (as of Warning Number 26) Here’s what the computer models are showing According to the JTWC, satellite imagery depicts consolidated core convection associated with a robust poleward outflow channel. TC 26S is expected to accelerate southeastward through the forecast period within the mid-latitude westerly flow poleward of a deep-layered subtropical ridge positioned to the northeast. The system will begin extra-tropical transition (ett) near 12 hours, and will quickly complete ett by 36 hours as it becomes embedded within the westerlies and gains frontal characteristics. TC 26S will weaken steadily after 12 hours as it encounters strong 25-35 knots and tracks over southwestern Australia.

Tropical Cyclone 28P
Sustained 35 knot winds…with gusts to 45 knots (as of Warning Number 1) Here’s what the computer models are showing According to the JTWC, satellite imagery depicts a consolidating system with well-organized core convection and convective banding. Earlier radar imagery from New Caledonia had shown an eye feature and current radar imagery still shows tightly-curved banding wrapping into a well-defined low-level circulation center. Despite the system’s hybrid nature and location within fairly strong northwesterly flow, and persistent low to moderate 15-20 knot wind shear, TC 28P was able to develop persistent central convection and spiral banding over the northeast, east and southwest quadrants. TC 28P is expected to be a short-lived system as it tracks southeastward within the persistent northwesterly flow along the southwestern periphery of a deep-layered subtropical ridge. Wind Shear is expected to increase to 35 knots by 24 hours, which will produce steady weakening and dissipation no later than 24 hours.     https://www.nrlmry.navy.mil/htdocs_dyn_apache/PUBLIC/tc_pages/thumbs/medium/tc21/SHEM/91S.INVEST/ir/geo/1km_bw/20210410.140000.SH912021.ahi.himawari-8.Infrared-Gray.25kts.100p0.1p0.jpg There’s a tropical disturbance being referred to as Invest 91S, which is located approximately 314 NM southwest of Christmas Island Here’s was the computer models are showing According to the JTWC, satellite imagery reveals disorganized cycling convection in the eastern periphery of a broad, elongated low level circulation center. Invest 91S is in a marginal environment for tropical development with minimal poleward outflow and high 20-25 knot wind shear, which is slightly offset by warm sea surface temperatures. Global models are in general agreement that invest 91S will track east-southeast over the next 24-48 hours with minimal development. 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 remains low.     https://www.nrlmry.navy.mil/htdocs_dyn_apache/PUBLIC/tc_pages/thumbs/medium/tc21/WPAC/94W.INVEST/ir/geo/1km_bw/20210410.140000.WP942021.ahi.himawari-8.Infrared-Gray.15kts.100p0.1p0.jpg There’s a third tropical disturbance being referred to as Invest 94W, which is located approximately 632 NM south of Guam Here’s was the computer models are showing According to the JTWC, satellite imagery shows fragmented banding wrapping into a weak low level circulation with cycling convection in the northern and southern semi-circles. Invest 94W is in a favorable environment for tropical development with robust westward outflow aloft, low 5-10 knot wind shear, and warm sea surface temperatures. Global models are in general agreement that the circulation in association with invest 94W will consolidate as it tracks to the northwest over the next 24-36 hours. Maximum sustained surface winds are estimated at 13-18 knots. The potential for the development of a significant tropical cyclone within the next 24 hours remains low.   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!
