934 WTNT42 KNHC 200245 TCDAT2 Tropical Depression Two Discussion Number 3 NWS National Hurricane Center Miami FL AL022026 1000 PM CDT Sun Jul 19 2026 The depression is producing a small area of deep convection near and north of the apparent center, with other modest bands mostly in the eastern semicircle. Since the various satellite intensity estimates are unchanged and the nearby surface observations haven't reported much more than 20 kt, the initial intensity will remain 25 kt for this advisory. This is also consistent with a just-received partial scatterometer pass. The system is drifting to the north-northwest, caught in light steering between a ridge over the western Atlantic and one over the south-central United States. Most of the guidance suggests that this slow motion, with some turn to the west-northwest, will continue early this week, and the cyclone's outer bands could bring tropical storm conditions to portions of the Florida Panhandle beginning late Monday. A turn to the west and an increase in forward speed are forecast late on Tuesday as the ridge over the U.S. builds eastward, causing the system to move along or just offshore of the northwestern Gulf coast during the middle and latter portions of the week. The track has been shifted a bit to the north in the short-term, blending back with the previous forecast on day 2, then a bit to the south at long-term. This is consistent with the latest model consensus and Google DeepMind solutions. Only slow strengthening of the system is expected due to its broad structure, pockets of mid-level dry air, and northeasterly vertical wind shear, despite very warm waters. The cyclone is still forecast to become a tropical storm on Monday when it is offshore of the Florida Panhandle. An increase in shear is expected by Tuesday, which could cause the intensity to flat line, along with some land interaction. This is a challenging forecast because of the expected moderate shear conditions, which are known to result in less predictable outcomes. For instance, reliable models are spread from near dissipation by the ECMWF/HAFS guidance but near hurricane-strength in the latest HWRF/HMON runs. The NHC forecast continues to lie between those solutions, but it should be mentioned that I don't have much confidence in this prediction given the above factors. Key Messages: 1. The depression is expected to gradually strengthen and could bring tropical storm conditions to portions of the Florida Panhandle beginning late Monday, where a Tropical Storm Watch is in effect. 2. Interests in Alabama, Mississippi, Louisiana, and Texas should monitor the progress of this system, as watches could be required for portions of that area over the next day or two. 3. Areas of flash flooding will be possible through Thursday along the eastern and central Gulf Coast from western Florida to southern portions of Alabama, Mississippi, and Louisiana.
