On Wednesday, Tropical Storm Arthur gained strength, boasting maximum sustained winds of 45 mph as it hit the Texas coastline near Galveston, leading to storm surges, coastal flooding, and a growing flash flood emergency across Texas, Louisiana, and Mississippi. The National Hurricane Center has cautioned coastal residents to prepare for potentially life-threatening flooding. Some regions have already seen more than 6 inches of rainfall, with predictions indicating total amounts could soar to 20 inches before Arthur weakens. Atlanta is also preparing for a significant Level 3 rainfall threat on Friday. Residents from the Gulf Coast to Georgia are advised to complete their emergency preparations immediately.
