Analysis
A Tropical Depression Forms Along the US Gulf Coast
A tropical depression has formed along the US Gulf coast, bringing the threat of heavy rain and storm surge flooding. The depression, named Tropical Storm Bertha, is expected to make landfall in south-east Louisiana on Wednesday, with widespread rainfall totals of 2-4in and isolated amounts of up to 8in expected.
The National Hurricane Center (NHC) has issued a storm surge watch from the Alabama-Florida border westward to the mouth of the Mississippi River in Louisiana. A tropical storm watch has also been issued from the Mississippi-Alabama border to the line separating Louisiana's Jefferson and Plaquemines parishes.
The NHC warns that the storm surge watch indicates a risk of life-threatening coastal flooding from rising water moving inland from the shoreline within the next 48 hours. Combined with high tide, storm surge could flood normally dry coastal areas along parts of the northern Gulf coast. Water levels could rise by 2-4ft (60-120cm) from the mouth of the Mississippi River to the Alabama-Florida border, with 1-3ft of surge possible across portions of coastal Louisiana and Florida, including Lake Pontchartrain.
In addition to the storm surge, the depression is also expected to produce widespread rainfall totals of 2-4in, with isolated amounts of up to 8in through Friday from western Florida to the middle Texas coast. The heavy rain could trigger flash flooding in some areas, while an isolated tornado or two is possible across Florida's Big Bend region.
Meanwhile, Tropical Storm Fausto continues to strengthen over the eastern Pacific. As of Monday morning, the storm was moving west-northwest at about 13mph with maximum sustained winds of 65mph. It is forecast to become a hurricane later Monday, with additional strengthening expected over the next few days.
Although no coastal watches or warnings are in effect for Fausto, the NHC warns that swells generated by the storm are expected to reach the west coast of the Baja California Peninsula on Wednesday and persist for several days. The swells are likely to create life-threatening surf and rip current conditions.
Fausto is forecast to continue tracking west-northwest through Wednesday.
