Tropical Storm Bertha is moving toward the densely populated U.S. Gulf Coast, with landfall expected Wednesday evening in southeastern Louisiana. 5 The storm's center is positioned approximately 145 miles southwest of Panama City 5 and 75 miles east of the Mississippi River mouth. 5
Maximum sustained winds are reported at 50 mph, 345 after increasing by 10 mph since the system formed Monday evening. 4 Tropical storm warnings extend from the Florida-Alabama border westward to portions of Louisiana. 34 Wind speed is currently 5 mph as the system moves northwest. 4
Bertha poses multiple threats to coastal communities. Storm surge warnings span from the Alabama-Florida boundary to the Mississippi River mouth, 4 with surge heights potentially reaching 4 feet in affected areas. 2345 Rainfall is expected to reach 3 to 5 inches along the Louisiana coast, 235 with some localities potentially experiencing up to 8 inches. 1 Isolated locations may face 4 inches of precipitation, creating the possibility of urban flooding. 5
In preparation, coastal communities are implementing defensive measures. Mississippi's Harrison County has opened six sand bag distribution points. 5 Beaches have been closed in the region. 5
Meanwhile, Hurricane Fausto has formed in the eastern Pacific, located approximately 745 miles southwest of the Baja California Peninsula. 123 The system maintains maximum sustained winds of 75 mph 123 and poses no direct coastal threat. 23 However, Fausto may generate dangerous waves and rip currents in the region. 2 Bertha marks the second tropical storm of the Atlantic hurricane season. 5
