@tswx3: Tropical Weather Advisory for Friday October 9, 2026. Tropical Weather Advisory #21: For Hurricane Isaias: Summary: ...ISAIAS RAPIDLY WEAKENING WHILE MOVING OVER THE WESTERN FLORIDA PANHANDLE... ...DAMAGING WINDS AND FLASH FLOODING THREAT SPREADS INLAND... Discussion: Isaias made landfall as a 90-kt hurricane at 0130 UTC near Destin Florida. Since that time, the radar structure of the storm has continued to degrade as strong vertical wind shear disrupts the circulation. However, Eglin AFB (KEVX) radar data and surface observations indicate damaging, gusty winds are persisting in the residual northern eyewall and in a band wrapping around the western side of the circulation. Now that the system is farther inland and losing organization, the initial intensity is lowered to 80 kt for this advisory. Isaias is rapidly losing tropical characteristics, and it is forecast to become post-tropical within the next 12 h while it continues moving quickly northward through Alabama. Although the sustained surface winds associated with Isaias will quickly weaken now that the storm is inland, damaging wind gusts associated with the system are expected to extend well inland through Saturday, especially in areas of higher terrain. Because of this, the gust factors in the forecast have been slightly increased during the first 24 h. A turn toward the northeast is forecast later this weekend, bringing the center of the system into the Tennessee Valley before it dissipates. Next intermediate advisory at 100 AM CDT. Next complete advisory at 400 AM CDT.
