Subtropical Storm Debby Discussion Number 3

11:00 PM AST Tue Aug 7 2018

There is nothing new to report with Debby tonight. The storm consists of a cloud-free center and a band of moderately intense convection to the south. Satellite intensity estimates were ST2.5/35kt from TAFB and ST2.8/41kt from UW-CIMSS ADT. A 0035z ASCAT pass showed winds near 35kt to the east of the center as well, so the initial intensity is left at that value. No intensification is expected over the next 2 days as Debby progresses over cooler ocean temperatures, with dissipation expected on Thursday as it becomes embedded within an approaching upper-level trough. This trough is currently steering the storm north but should whisk Debby toward the northeast before destroying its circulation. The updated forecast is not appreciably different from the last.
