Tropical Storm Bertha strengthened over the Gulf of Mexico on Tuesday as coastal communities from Florida to Louisiana prepared for heavy rain, dangerous surf, possible storm surge and isolated tornadoes.
The storm was moving slowly toward the northern Gulf Coast, with tropical storm warnings and storm surge watches in effect for parts of the region. As of Tuesday morning, Bertha was about 110 miles south of Panama City, Florida, and 170 miles southeast of Mobile, Alabama, with maximum sustained winds of 50 mph, according to the National Hurricane Center.
Forecasters said Bertha had gained strength since forming Monday night and was moving northwest at about 5 mph. A tropical storm warning was in effect from the Florida-Alabama border to the Jefferson and Plaquemines parish line in Louisiana, meaning tropical storm conditions were expected within the warning area.
The National Weather Service also warned that Bertha could bring tropical storm conditions to parts of the Florida Panhandle and Alabama coast through Wednesday, with storm surge and heavy rainfall among the main concerns.

Storm surge watches were issued from the Alabama-Florida border to the mouth of the Mississippi River. Forecasters said some coastal areas in Louisiana, Alabama and Florida could see potentially life-threatening surge of up to 4 feet if the storm pushes water inland at high tide.
The storm is expected to remain near or along the northern Gulf Coast this week, bringing periods of heavy rain to coastal Florida, Alabama, Mississippi and Louisiana before pushing westward toward Texas. Flash flooding could be possible through Friday from western Florida to middle Texas.
Rainfall totals along parts of the Louisiana coast could reach 3 to 5 inches, with higher amounts possible in isolated locations. Even moderate rainfall can become dangerous in low-lying coastal communities when drainage systems are overwhelmed or when water is pushed inland by storm surge.
Bertha may also produce one or two isolated tornadoes over Florida’s Big Bend region, forecasters said. Tornadoes associated with tropical systems can form quickly and may be difficult to track, making local weather alerts especially important for residents in the warning area.
Local preparations were already under way in several communities. Red flags were posted at Orange Beach, Alabama, warning swimmers about high surf and dangerous currents. In Escambia County, Florida, officials offered sand for residents in flood-prone areas to fill sandbags.
Bertha is the second named storm of the Atlantic hurricane season, following Tropical Storm Arthur, which brought heavy rain to parts of the southeastern United States in June.
The storm’s slow movement is one reason forecasters are emphasizing flooding. A fast-moving tropical storm can bring damaging wind but leave quickly. A slower system can repeatedly push rain bands over the same communities, increasing the risk of street flooding, washed-out roads and rising water around homes and businesses.
Residents in coastal areas should not focus only on the storm’s wind speed. Tropical storms can cause serious damage through water, especially storm surge and inland flooding. Drivers are also urged not to cross flooded roads, since water depth and road damage can be difficult to judge.
The Gulf system is not the only storm forecasters are monitoring. In the eastern Pacific, Hurricane Fausto was far from Mexico’s Baja California peninsula and was not expected to threaten land directly. However, forecasters said its ocean swells could create dangerous surf and rip currents along parts of the Baja coast.
Why It Matters
Bertha may not be a hurricane, but tropical storms can still create dangerous conditions for families, tourists, businesses and emergency crews. Storm surge, flash flooding and rip currents can become life-threatening even when winds remain below hurricane strength.
For Gulf Coast communities, the storm arrives during a busy summer travel period, when beaches, campgrounds and coastal roads may be crowded with visitors unfamiliar with local flood risks.
What Comes Next
Forecasters will continue tracking Bertha’s path, strength and rainfall potential as it moves near or along the northern Gulf Coast. Watches and warnings may change quickly depending on the storm’s track.
Residents and visitors in affected areas should follow local emergency alerts, avoid flooded roads, stay out of dangerous surf and prepare for possible power outages or travel disruptions through the end of the week.
Tropical Storm Bertha is expected to bring heavy rain, storm surge and flash flooding risks along the Gulf Coast.
