NASA Sees System 91S Struggling
NASA/Goddard Space Flight Center
NASA's Aqua satellite provided infrared data on System 91S in the Mozambique Channel that showed a system battered by wind shear, stretched out, with broken convection.
On January 31, System 91S had maximum sustained surface winds between 20 to 25 knots/37.0 to 46.3 kph/23.0 to 28.7 mph. Minimum sea level pressure was estimated to be near 1004 millibars.
Vertical wind shear continues to batter the tropical low, and the Joint Typhoon Warning Center expects the system to weaken as it moves south through the Mozambique Channel (between Mozambique on the African mainland and the island nation of Madagascar).
The Joint Typhoon Warning Center gives System 91S a low chance of development as it continues to deal with moderate to strong wind shear over the next couple of days.
