Tropical Storm Bertha, the second named storm of the 2020 Atlantic hurricane season, tracked across the Gulf of Mexico in late May 2020, bringing heavy rainfall and flood risks to the U.S. Gulf Coast. The system prompted tropical storm warnings for coastal areas from the Florida Panhandle to Louisiana as it moved slowly toward landfall.
Storm Path and Meteorological Status
As of late May 2020, the National Hurricane Center (NHC) tracked Tropical Storm Bertha approximately 120 miles southwest of Panama City, Florida, and 105 miles southeast of Mobile, Alabama. The storm maintained maximum sustained winds of 60 mph while moving westward at 6 mph. Meteorologists projected the system would make landfall in a sparsely populated region of southeastern Louisiana before weakening as it moved inland.
According to the National Weather Service in Louisiana, wind represented the primary threat to the region during the storm’s approach. Forecasters anticipated that Bertha would produce between 2 and 4 inches of rain across a wide area from the Florida Panhandle to southern Louisiana, with isolated pockets receiving higher totals that could trigger flash flooding in urban environments.
Coastal Impacts and Emergency Measures
The NHC issued tropical storm warnings for the northern Gulf Coast, including New Orleans, effective through Wednesday, May 27, 2020. Authorities warned of potential storm surges reaching up to four feet in areas stretching from the mouth of the Mississippi River to the Alabama border.
In response to the incoming weather, officials in Mississippi, Louisiana, and Florida established distribution centers for sandbags to assist residents in flood-prone zones. Local authorities implemented safety restrictions, including:
- Beach Safety: Red flags were raised at multiple beaches to signal dangerous rip currents.
- Water Access: Officials prohibited entry into the water across several sectors of the Gulf Coast.
- Public Preparedness: Residents in low-lying areas were encouraged to utilize sandbag resources to mitigate property damage from expected rainfall.
Seasonal Context and Parallel Systems
Bertha followed Tropical Storm Arthur, which impacted the southeastern United States earlier that month. While the National Oceanic and Atmospheric Administration (NOAA) had issued an initial seasonal outlook calling for a below-average hurricane season, the agency emphasized that such projections do not preclude the formation of high-impact cyclones.
Simultaneously, in the Pacific Ocean, Hurricane Fausto moved away from the Baja California peninsula. The NHC reported that Fausto was located 780 miles southwest of the southern tip of Baja California with sustained winds of 75 mph. Although the storm did not trigger coastal watches or warnings for land, the NHC advised that swells generated by the hurricane could cause hazardous rip currents along the Baja California coast.
