Track of TC 19P

Tropical Cyclone Sandra (19P) will gradually weaken as strong vertical wind shear (VWS) persists and sea surface temperatures (SSTs) drop to below 25 Celsius after TAU 24.

There is a distinct possibility that Sandra will dissipate before end of forecast due to the high VWS and low SSTs. The JTWC forecast is laid with high confidence close to model consensus despite the moderate spread in the available numeric guidance. Maximum significant wave height is 23 feet.
