#1148769 (Received by flhurricane at: 4:38 PM 21.Aug.2023) TCDAT1 Tropical Depression Gert Discussion Number 10 NWS National Hurricane Center Miami FL AL062023 500 PM AST Mon Aug 21 2023 Gert continues to be sustained by a very small but persistent area of convection east of its surface wind center. ASCAT data that came in 5 minutes after the release of the previous advisory showed peak winds of just above 25 kt well to the north of Gert`s center. South of Gert is mostly light and variable winds. Assuming Gert has weakened further a little since then, its intensity has been lowered to 25 kt. All models continue to suggest that Gert will struggle in the face of strong upper-level winds and a very dry surrounding environment. The small tropical depression will likely either lose organized deep convection and become a remnant low or dissipate at almost any time. There is a chance that Gert could persist as a remnant low beyond the 24 h shown in the NHC forecast, but it is unlikely that Gert will have sufficient organized deep convection to be classified as a tropical cyclone in that case. Gert is moving west-northwestward, but the depression or its remnants should turn more northwestward by tomorrow. No noteworthy changes were made to the NHC track or intensity forecasts with this advisory.
