Tropical Storm Colin was downgraded to a tropical depression after only one day as a minimal tropical storm when upper level wind shear caused Colin's demise. NASA's Tropical Rainfall Measuring Mission satellite captured an image of the storm's waning rainfall at 9:47 p.m. EDT on August 3.
When the TRMM satellite, a mission managed by both NASA and the Japanese Space Agency, JAXA, flew over Colin late on August 3 it was just a few hours after the National Hurricane Center issued their last advisory on the system. TRMM's rainfall analysis showed that there was very little left of Colin except a relatively small area of widely scattered light to moderate showers.
By 8 a.m. today, August 4, Colin had become a remnant low pressure area. The center of the remnant low was located about 150 miles east northeast of the Leeward Islands, near 17.0 North and 57.0 West. Colin's remnants continue to move west northwestward at 20 to 25 mph.
Although the National Hurricane Center noted that there's a 10% chance that Colin could become a tropical storm again in the next 48 hours, it is still expected to bring heavy rains and gusty winds to the parts of the Leeward Islands and the Virgin Islands today and tonight. Upper level winds continue to batter the storm, preventing it from regenerating today.
