Tropical Storm Bertha brings coastal flooding to Louisiana and feeds a significant flood threat across the Mid-Atlantic region.

Tropical Storm Bertha made landfall in St. Bernard Parish, Louisiana, on July 22, bringing coastal flooding to New Orleans and the surrounding Gulf Coast. While the storm is expected to maintain tropical storm strength until it dissipates over Texas by Friday, its most significant impact may be felt hundreds of miles away. A plume of tropical moisture from Bertha is feeding into a cold front across southeast Virginia, parts of the Carolinas, and northern Georgia. This moisture is expected to produce heavy rainfall, potentially delivering a month's worth of rain in just a few days. While the strong El Niño pattern is expected to limit the total number of storms this season, unusually warm Atlantic waters provide high-octane fuel for potential power. Experts note that while the frequency of storms may decrease, the percentage of powerful category 4 and 5 hurricanes has increased over the last 30 years. Residents are encouraged to prepare evacuation plans and review insurance policies to mitigate potential damage from the ongoing season.
