Track of TC 19P

Tropical Cyclone Sandra (19P), located approximately 350 nm northwest of Noumea, New Caledonia, has tracked south-southeastward at 05 knots over the past six hours.

Animated infrared (IR) satellite imagery indicates that the system has weakened over the past 12 hours with deep convection decreasing in areal extent. A METOP-A image depicts a well-defined center with a microwave eye feature; however, deep convective banding has become more fragmented. There is good confidence in the initial position based on this image.

The initial intensity is assessed at 90 knots based on the lower end of Dvorak intensity estimates ranging from 90 to 102 knots. Maximum significant wave height is 30 feet.
