Track of TC 19P

Tropical Cyclone Sandra (19P), located approximately 615 nm northwest of Noumea, New Caledonia, has tracked east-southeastward at 04 knots over the past six hours.

Animated multispectral satellite imagery (MSI) shows deep convection wrapping around the western and northern semi-circles of a developing yet ragged and poorly defined eye. There is high confidence in the initial position based on the eye feature in the MSI and an AMSU-B microwave image.

The initial intensity is based on congruent Dvorak estimates of 65 knots from PGTW and KNES. Upper-level analysis indicates the system is just west of a point source anticyclone in an area of light (05-10 knot) vertical wind shear (VWS) with favorable polar and equatorward outflow.
