Tropical Storm Bertha in the Gulf of Mexico is moving toward the Florida Panhandle and Alabama

The wind speed increased by 10 mph (16 kph) since Bertha formed Monday night. A tropical storm warning, meaning the conditions are expected within the warning area within 36 hours, was in effect early Tuesday from the Florida and Alabama border to the Jefferson and Plaquemines parish line in Louisiana.

A storm surge watch, indicating rising, possible life-threatening water moving inland from the coast within 48 hours, was issued from the Alabama and Florida border to the mouth of the Mississippi River, the hurricane center reported.

Bertha is expected to stay near or along the Gulf Coast

Bertha is the second tropical storm of the Atlantic hurricane season after Tropical Storm Arthur brought heavy rainfall to the southeastern U.S. in June.

The storm was expected to stay near or along the northern Gulf Coast this week, dropping heavy rain on coastal areas of Florida, Alabama, Mississippi and Louisiana while pushing west toward Texas.

Potentially life-threatening storm surges of up to 4 feet (1.2 meters) are possible in portions of Louisiana, Alabama and Florida, the hurricane center said, warning Bertha could spin off an isolated tornado or two over the Florida Big Bend region.

Areas of flash flooding also will be possible through Friday along the coast from western Florida to middle Texas, forecasters said, adding that rainfall could total 3 to 5 inches (7 to 12 centimeters) along the Louisiana coastline, with higher amounts in some scattered areas.

Red flags on the beach at Orange Beach, Alabama, cautioned swimmers about high surf and currents. In Escambia County, Florida, emergency officials offered sand for people living in flood-prone areas to use for sandbags.

Hurricane Fausto churns in the Pacific

In the eastern Pacific Ocean, Hurricane Fausto churned far from Mexico’s Baja California peninsula and posed no threat to land, the hurricane center said.

Fausto gained hurricane status Monday night. It was about 740 miles (1,191 kilometers) southwest of the southern tip of the Baja California peninsula, had top sustained winds of 80 mph (129 kph) and was moving northwest at 12 mph (19 kph).

The storm was expected to strengthen Tuesday and Wednesday. No coastal watches or warnings were in effect, though ocean swells generated by the storm could cause life-threatening surf and rip tide conditions on the Baja California coast, the center said.
