The primary impacts of Tropical Storm Bertha include heavy rainfall, gusty winds, storm surge, and coastal flooding. Coastal areas from Louisiana to Texas are at risk of inundation, with low-lying properties, homes, and businesses particularly vulnerable. Flash flooding may occur in urban areas due to rainfall totals of up to 6 inches. Swells generated by the storm are expected to cause life-threatening surf and rip current conditions along the northern and northwestern Gulf Coast. Inland areas may experience wind gusts of 20-30 mph, while coastal counties could see gusts up to 40 mph.
