Isaias weakens but flooding threat persists

The storm moved inland across Alabama with maximum sustained winds down to 35 mph early Saturday, positioned about 25 miles south-southwest of Montgomery. All tropical storm and storm surge warnings were discontinued, but forecasters warned of 4 to 8 inches of rain across southern Alabama, the Florida Panhandle, and the Big Bend through the weekend.

More than 911,000 customers in Florida, Alabama, and Georgia were without power early Saturday, according to poweroutage.us data cited in the reporting. Roads in Destin were flooded, Pensacola police warned residents off streets covered in debris, and several Panhandle counties temporarily suspended emergency response Friday night.

In southern Alabama, officials in Mobile reported downed trees and power lines, and roads in Houston County were closed. The storm is expected to move into the Tennessee Valley and then bring heavy rain to the Southeast, Midwest, and Northeast into Monday. Tornadoes remain possible across the Florida Panhandle, Georgia, and the Carolinas.

Florida Governor Ron DeSantis told residents to stay put at a Friday news conference, saying the storm was here and drivers should not be on the roads. The storm grounded most Friday flights at Panhandle airports, including all flights in and out of Destin-Fort Walton Beach.

For freight, the disruption is concrete. FreightWaves SONAR data shows tender rejections and spot rates rising noticeably in the Mobile and Montgomery, Alabama markets, with inbound truckload rejections climbing sharply versus the national average. Carriers should expect rate volatility and possible road closures on Gulf Coast lanes until the water recedes.

Drivers already in the region should check state DOT road condition pages before rolling, keep fuel topped up in case of detours, and never attempt flooded roadways. Six inches of moving water can knock a person down; twelve inches can carry a vehicle, and a loaded semi is no exception in fast water.

Isaias was the first hurricane to hit the eastern U.S. since Milton in 2024. Meanwhile, Hurricane Simon strengthened to Category 4 off Mexico's coast and Tropical Storm Rachel threatened northern Mexico and Southern California. It is an unusually busy stretch for storm-season freight planning.

Recovery freight typically follows within days: bottled water, generators, building materials, and fuel move first. Carriers positioned near the affected region may see a short-term bump in emergency and rebuilding loads. Watch load boards for FEMA and relief-agency postings, and confirm rates before accepting, since urgency can cut both ways on pricing.

Fuel availability is the other immediate concern. With power out across the region, some fuel stations cannot pump, and drivers should top off before entering the affected area rather than counting on stops inside it. Carrying extra drinking water and checking in with dispatch on a schedule are basic precautions that matter most when infrastructure is degraded.

The situation remains fluid. Drivers should monitor National Hurricane Center updates and local emergency management channels through the weekend before committing to Gulf Coast routes. This article will be updated as conditions change.
