Tropical Cyclone 18S is located approximately 160 NM south-southwest of Learmonth, Australia

Tropical Cyclone 18S Sustained 35 knot winds…with gusts to 45 knots (as of Warning Number 18) According to the JTWC, satellite imagery depicts flaring deep convection east of a defined level circulation center. Looping radar images from Learmonth, Australia Environmental analysis indicates unfavorable conditions with high20-25 knot wind shear and marginal sea surface temperatures. TC 18S will continue tracking south, with increasingly strong 30-45 knot wind shear. TC 18S is expected to slightly intensify and gradually transition into a subtropical cyclone. There’s a tropical disturbance being referred to as Invest 90S, which is located approximately 900 NM west of Cocos Islands Here’s what the computer models are showing According to the JTWC, satellite imagery shows a consolidating low level circulation with flaring convection aloft. Environmental analysis indicates that Invest 90S is in a favorable environment for development, with warm sea surface temperatures, good diffluence aloft…and moderate 20-25 knot wind shear. Global models are in good agreement that invest 90S will continue to track southtward over the next 24 hours. 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.   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!
