Tropical Storm Bertha is 35 miles south-southwest of Biloxi Mississippi and 60 miles east of New Orleans, Louisiana. The system is moving west-northwest at 7 mph, with maximum sustained winds of 45 mph.

“… the center of Bertha will move near or along the Louisiana and upper Texas coasts through Thursday, and then move farther inland into Texas on Friday,” analysts explained. They also said “Additional weakening is forecast during the next couple of days, but Bertha could maintain tropical storm intensity through late Thursday.”

Forecasters alert of a tropical storm watch and a tropical storm warning extended for westward along the Louisiana coast.

Meaning of the different watches and warnings

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within the next 12 to 36 hours.

Hazards affecting land

Wind. Tropical storm conditions will continue spreading across portions of the northern Gulf Coast within the warning area today. Tropical storm conditions are possible within the watch area in Louisiana by tonight and along the upper Texas coast by Thursday or Thursday night.

Storm surge. The combination of storm surge and the tide will cause normally dry areas near the immediate coast to be flooded by rising waters moving inland from the shoreline. The water could reach the following heights above ground somewhere in the indicated areas if the peak surge occurs at the time of high tide…

Alabama/Florida border to Port Bolivar, TX…1-3 ft Lake Pontchartrain…1-3 ft

The deepest water will occur along the immediate coast. Surge-related flooding depends on the relative timing of the surge and the tidal cycle, and can vary greatly over short distances.

For a complete depiction of areas at risk of storm surge inundation, please see the National Weather Service Peak Storm Surge Graphic, available at hurricanes.gov/graphics_at2.shtml?peakSurge.

Rainfall. Bertha is expected to produce total rainfall amounts of 1 to 4 inches with isolated higher totals of 6 inches through Friday along the central to western Gulf Coast from Northwest Florida to southern Texas. This rainfall may produce isolated flash flooding, especially in urban areas.

For a complete forecast of rainfall associated with Bertha, please see the National Weather Service Storm Total Rainfall Graphic available at hurricanes.gov/graphics_at2.shtml?rainqpf and the Flash Flood Risk graphic at hurricanes.gov/graphics_at2.shtml?ero.

Surf. Swells generated by Bertha will continue spreading westward along the northern Gulf Coast during the next few days. These swells are likely to cause life-threatening surf and rip current conditions.
