Tropical Cyclone 09S (Grant) 

According to the JTWC warning number 18, sustained winds are 50 knots with 65 knot gusts

Tropical cyclone 09S (Grant) continues to maintain compact structure with deep convection wrapping tightly around the low level circulation center as depicted by animated enhanced infrared (eir) satellite imagery.

Cloud top temperatures have cooled over the past six hours with most activity in the northern semicircle. A 251202z sentinel-1c sar image supports the initial position and indicates a 43 knot mean vmax, with a peak value of 55 knots over the southeastern quadrant.

Tropical cyclone 09S (Grant) will continue tracking westward under the influence of subtropical ridging to the south while struggling against moderate vertical wind shear (20-25 kts) and dry air intrusion.

These forecast conditions will only allow the system to intensify up to 55 kts around 36 hours. After 72 hours the decrease in forecast vertical wind shear and a better outflow will allow the circulation to undergo another period of intensification with a peak intensity expected to reach 75 kts by 120 hours.
