Key points

Isaias became a hurricane at about 10:30 p.m. CDT Wednesday. By 4 a.m. CDT Thursday the National Hurricane Center put its top winds near 80 mph, with the pressure down to 979 millibars from 994 at Wednesday's 7 p.m. advisory.
The watches became warnings overnight. A Hurricane Warning runs from Ocean Springs, Mississippi, to the Bay/Gulf County Line in Florida. A Storm Surge Warning runs from the mouth of the Mississippi River to the Steinhatchee River, Florida, with 5 to 7 feet possible from Ocean Springs to Indian Pass and in Mobile Bay.
The Center still expects landfall within the warning area late Friday or early Saturday. Its 4 a.m. forecast has a peak near 110 mph early Friday and some weakening before landfall. Flood Watches from Mobile and Tallahassee cover Friday afternoon into Saturday, with 3 to 7 inches of rain and local totals up to 10.

Isaias overnight: a hurricane, and the warnings go up

Isaias spent Wednesday night working its way east-northeast across the southern Gulf, and the hurricane hunters never left it. At 10 p.m. CDT the Hurricane Center had it at 70 mph and 988 millibars. Right after that advisory, an Air Force Reserve crew dropped an instrument into the southwest side of the storm and measured winds strong enough for the Center to call it a hurricane at 10:30 p.m. A NOAA crew took over after that. By 4 a.m. Thursday, Isaias had 80 mph winds and a pressure of 979 millibars. The 4 a.m. headline read: "NOAA Hurricane Hunters indicate that Isaias continues to intensify."

The 10 p.m. advisory turned the watches into warnings. The Hurricane Watch became a Hurricane Warning from Ocean Springs, Mississippi, to the Bay/Gulf County Line in Florida. That stretch covers Mobile Bay, Pensacola, the Okaloosa coast and Panama City. The Storm Surge Watch became a Storm Surge Warning from the mouth of the Mississippi River to the Steinhatchee River. Tropical Storm Warnings went up on both sides, west to the Jefferson/Plaquemines Parish line in Louisiana and east to the Aucilla River in Florida. The 1 a.m. and 4 a.m. advisories changed nothing.

The local offices carried the warnings inland. Mobile's 10:17 p.m. CDT statement extended the Hurricane Warning to inland Mobile, Baldwin, Escambia, Santa Rosa and Okaloosa counties. New Orleans put up Tropical Storm Warnings for inland Hancock, Harrison and Jackson counties in Mississippi, and the Hurricane Watch for northern Jackson County stays in place. At 5:58 a.m. EDT, Tallahassee raised the inland Panhandle from a Tropical Storm Watch to a Tropical Storm Warning, from Walton County east to Liberty, Franklin and Wakulla. Its explanation: the wind field "may be lopsided towards the east, which means impacts are likely well beyond the forecast cone."

The 4 a.m. discussion was candid about the intensity forecast. It called it "somewhat tricky": Isaias has been strengthening through about 20 knots of wind shear, and "an eyewall keeps coming and going in aircraft fixes." The Center brings it to "just shy of major hurricane intensity" in 24 hours. It then expects shear to rise to 40 to 50 knots in the last day before landfall, which "will likely impart some weakening." Its next line: "Isaias is expected to remain a dangerous hurricane through landfall."

Rain is the part that reaches farthest. Tallahassee's 2:38 a.m. EDT Flood Watch covers southeast Alabama, the Florida Panhandle and Big Bend, and southwest Georgia from Friday afternoon through Saturday evening, with "widespread totals of 3 to 7 inches" and local 10-inch amounts. Its storm statement adds that "soggy conditions across the region from recent rainfall" leave the ground more sensitive to flooding. Mobile's Flood Watch covers the Alabama coast and the western Panhandle from Friday afternoon through Saturday afternoon. The Center also lists isolated tornadoes as possible Friday night near the coast of Alabama, the Florida Panhandle and far southwest Georgia, and on Saturday farther inland.

At 4 a.m., Isaias sat about 540 miles south-southwest of Mobile, about 580 miles southwest of Panama City and about 460 miles south of New Orleans.

What the offices ask of people in the warning

The Hurricane Center's 4 a.m. advisory asks that preparations along the warning coast "be rushed to completion today." Its key messages ask residents of the Storm Surge Warning to "follow advice given by local officials and evacuate if told to do so," and people in the Hurricane Warning to "prepare for the possibility of long-duration power outages." Tallahassee says conditions on the Panhandle "could begin to deteriorate" as early as Friday morning. The federal preparedness guide is at https://www.ready.gov/hurricanes.
