As of the NHC’s 5 a.m. advisory, the center of Bertha was located about 110 miles south-southwest of Panama City and 170 miles southeast of Mobile, Alabama moving northwest at 5 mph with maximum sustained winds of 50 mph and higher gusts.
Tropical-storm-force winds extend outward up to 80 miles from Bertha’s center.
“A slow northwestward to west-northwestward motion is expected today followed by a turn westward by the middle part of this week,” said NHC senior hurricane specialist Philippe Papin. “On the forecast track, Bertha will move near or along the northern Gulf Coast during the next several days.”
The NHC issued a tropical storm warning for the coast from the Alabama/Florida border west to the Jefferson/Plaquemines Parish border in Louisiana while a tropical storm watch remains in Florida from the Bay/Gulf County line west to the Alabama border.

What had been the second tropical depression of the Atlantic hurricane season spun into a named storm by 8 p.m. Monday with 40 mph winds, but had picked up steam by 11 p.m.
Papin said it may intensify to as much as 60 mph sustained winds today, but models show it could fall apart within 48 hours.
“While sea-surface temperatures are plenty warm, nearby dry air could be imported by this shear into Bertha’s center,
disrupting its structure,” he said. “While periodic bursts of deep convection will likely continue to occur over the next 24-48 hours, the latest NHC intensity forecast only shows a slight additional intensification today before the shear becomes prohibitively strong.”

Tropical-storm conditions are expected within the warning area later Tuesday and into Wednesday while conditions are possible in the watch area in the Florida Panhandle later Tuesday.
A storm surge of 1-3 feet could hit the Florida coast from Indian Pass to Chassahowitzka while surge could hit 2-4 feet from the mouth of the Mississippi River to the Alabama-Florida border, and 1-3 feet from Morgan City, Louisiana to the Mississippi and Lake Pontchartrain.
In addition, rainfall of 2-4 inches through Thursday, with some areas seeing up to 6 inches, is forecast along the Gulf Coast and adjacent inland locations from western Florida into southern Louisiana, including southern portions of
Alabama and Mississippi, with a threat of flash flooding.
Swells along the coast could cause life-threatening surf and rip current conditions.
