NASA sees Tropical Storm Bertha leaving the Bahamas

August 20, 2014



By a News Reporter-Staff News Editor at Defense & Aerospace Week -- Tropical Storm Bertha took a "vacation" in the Bahamas on August 3 and NASA's Terra satellite captured an image of the storm that appeared be centered over "Crooked Island."

On August 2, before Bertha visited the Bahamas, the western half of the storm passed over Puerto Rico. A visible image captured by NASA's Terra satellite showed Bertha's clouds stretched from Puerto Rico east, over the British Virgin Islands. NOAA's National Weather Service office in San Juan, Puerto Rico reported 1.36 inches of rainfall from Bertha on August 2.

On August 3 at 15:35 UTC (11:35 a.m. EDT), the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite captured a visible image of Tropical Storm Bertha over the Bahamas. The visible image showed powerful thunderstorms around Bertha's center, and southeast of the center. Those powerful storms southeast of the center were being pushed there from wind shear coming from the northwest.

Forecaster Stewart at the National Hurricane Center or NHC noted in the Discussion on Bertha on August 4 at 5 a.m. EDT, "Convection has been pulsing near the center, but the overall convective cloud pattern of Bertha has changed little since the previous advisory due to moderate northwesterly wind shear."
