Tropical cyclone 22S (Halima), is located approximately 1012 NM southeast of Diego Garcia
According to the JTWC Warning number 19 sustained winds were 35 knots with gusts to near 45 knots.
Satellite imagery shows the low level circulation has become fully exposed as the associated convection and cirrus canopy has sheared further southwestward.
Analysis indicates an unfavorable environment with warm sea surface temperatures and strong poleward outflow offset by strong (25+ knot) relative vertical wind shear and cold dry air intrusion at the low levels.
TC Halima is expected to continue westward under the steering influence of the subtropical ridge to the southwest and weaken to below warning criteria by 12 hours.
