The parade of tropical impulses moving westward off of Africa into the tropical Atlantic that has produced Hurricanes Danielle and Earl, and Tropical Storm Fiona, has now yielded a new Tropical Depression, Number 9, that will become Gaston if it achieves Tropical Storm status. Some environmental conditions favor intensification, and... Read More
AWIPS images of 1-km resolution POES AVHRR visible channel 1 (0.63 µm) and channel 2 (0.86 µm) along with IR channel 4 (10.8 µm) data (below) showed Hurricane Earl moving northwestward, just to the northeast of the Bahamas, on 01 September 2010. Earl’s intensity decreased from a Category 4 to... Read More
