| #1158664 (Received by flhurricane at: 4:46 AM 24.Oct.2023) TCDAT1 Tropical Depression Twenty-One Discussion Number 3 NWS National Hurricane Center Miami FL AL212023 500 AM EDT Tue Oct 24 2023 Proxy-vis satellite imagery indicates that the center of Tropical Depression Twenty-One has moved inland over Nicaragua tonight. This was confirmed from both ASCAT B and -C scatterometer passes that depicted there was no circulation offshore. Infrared imagery indicates that deep convection remains just offshore. The initial intensity is held at 25 kt for this advisory. Since the center of the circulation has moved inland, the depression should become a remnant low or dissipate later today. Heavy rainfall with flash and urban flooding remain the primary impacts even as the system dissipates. The estimated motion is around 310/5 kt. The depression and then the remnants, are forecast to continue northwestward, and then generally head westward toward the eastern Pacific after that. KEY MESSAGES: 1. Heavy rains from the depression will continue to impact portions of Nicaragua through Tuesday night with heavy rainfall spreading into Honduras during the day on Tuesday. This rainfall is likely to produce flash and urban flooding, along with possible mudslides in areas of higher terrain.
