Tropical cyclone 22S (Halima), is located approximately 973 NM south-southeast of Diego Garcia
According to the JTWC Warning number 10 sustained winds were 45 knots with gusts to near 55 knots.
Satellite imagery shows a rapidly eroding system with all associated convection sheared
southeastward of the low level circulation.
Analysis indicates a highly unfavorable environment with warm sea surface temperatures and strong poleward outflow completely offset by strong vertical wind shear and cold dry air intrusion in the low levels. The cyclone is tracking along the southwestern periphery of the ridge to the northeast.
TC Halima will track more eastward then northeastward as the ridge extends westward. The highly unfavorable conditions will prevail along the track and continue to rapidly erode the system to dissipation by 48 hours, possibly sooner.
