The flooding in the Eastern U.S. has caused significant damage, with reports of fatalities and widespread disruption. Communities in low-lying areas are particularly vulnerable to flash flooding, which can occur rapidly and with little warning. In Louisiana, Bertha has already caused damage, and as it moves westward toward Texas, additional risks include heavy rainfall, strong winds, and potential power outages. Residents in affected areas should prepare for possible evacuations and monitor updates from local authorities.
