Tropical Depression Eight Forecast Discussion Number 3
2021-08-16 16:44:16| National Hurricane Center (Atlantic)
Issued at 1100 AM AST Mon Aug 16 2021 000 WTNT43 KNHC 161444 TCDAT3 Tropical Depression Eight Discussion Number 3 NWS National Hurricane Center Miami FL AL082021 1100 AM AST Mon Aug 16 2021 Although the center of the depression is embedded beneath deep convection, Dvorak estimates from TAFB and SAB are not a consensus T2.5 quite yet. Therefore, the depression is still estimated to be producing maximum winds of 30 kt. Very warm waters and low to moderate deep-layer shear are expected to support strengthening during the next couple of days. After 48 hours, strong northerly to northeasterly shear of 25-30 kt is likely halt any intensification. For the most part, the NHC intensity forecast is very close to the tightly clustered SHIPS, LGEM, HCCA, and IVCN aids. As we've seen in several cases this year, the HWRF is a notable high outlier, bringing the system to category 2 hurricane strength in 2-3 days. Given the expected shear, that solution does not appear likely at this point. The depression has been moving southward, or 185/8 kt, and it is expected to rotate around a mid-tropospheric high located over the western Atlantic. Track models are in general agreement that the system will make a clockwise loop in the coming days, with most of the disagreement being in how sharp the turn will be. In part due to the system's initial motion, the updated NHC track forecast now shows a wider, sweeping loop and is close to the TVCA consensus aid. It should be noted that the ECMWF and HCCA aids are even farther south and show an even more gradual turn.
