Hurricane Isaias has intensified into a well-developed Category 3 hurricane and is making its move toward the Gulf Coast.
Thankfully, the upper-level winds are somewhat hostile, or it would have gotten a lot stronger like Milton did two years ago.
The peak winds will likely decrease a bit later today as the system approaches landfall, but it won't change the impacts significantly.
Damaging winds, storm surge, and rain heavy enough to cause flooding will affect the entire Florida Panhandle beginning late this afternoon, peaking this evening.
Early today is the last chance to maneuver before the weather starts deteriorating this afternoon.
Overnight, strong winds, which will likely knock out power, and torrential rain will spread into Alabama, Georgia, and eastern Mississippi.
Tornadoes will also be a threat in the outer bands north and well east of Isaias's center, including Tallahassee, North Florida, and into Georgia.
The El Niño-driven jet stream ripping across the south will morph the storm into something of a comma shape. The worst weather is likely to be ahead of the center of circulation and in the tail of the comma well to the east.
The jet stream will energize torrential rain, and tornadoes are possible in both the head and tail of the storm as it moves inland.
Strong wind gusts are likely over a wide area, including the entire State of Alabama and most of Georgia, especially near and to the east of where the center of Isaias tracks.
Bad weather will arrive well in advance of the center, which will cross the coast mid to late evening on the current schedule.
Thunderstorms are likely along the I-10 corridor this afternoon with the worst weather arriving in the evening.
The threat of heavy rain and tornadoes will continue through the night and into tomorrow as the comma-shaped hurricane pushes north.
The hurricane will merge with a large upper-level low-pressure system to spread tropical moisture across the Southeast.
The combo system will draw moisture from the Atlantic as well as the Gulf, elevating the flood threat along the Carolina coast in addition to higher elevations well inland. Stay aware of flood alerts issued for your area.
Isaias will push Gulf water over the coast along a large portion of the northern Gulf. The National Hurricane Center is forecasting the tide to be up to 7 feet above normal height around the time of landfall.
That assumes that landfall occurs around high tide time. If the tide is lower, obviously the impact would be a bit diminished, but there isn't much tidal swing on the northern Gulf beaches.
Tomorrow is a big football Saturday across the Southeast. If you are attending a game, consider carefully before getting on the road. Trees might be down, power might be out, and flooding rain is likely in some areas.
