Tropical Storm Bertha is fading, but its moisture plume is fueling a serious East Coast flood threat
CNN • • general
Key Points:
- Tropical Storm Bertha is moving near the Louisiana and upper Texas coasts with sustained winds of 45 mph, expected to maintain strength until it reaches Texas before dissipating by Friday.
- Bertha's moisture is enhancing a cold front across the Mid-Atlantic and Southeast, leading to significant flooding risks that may surpass the storm's direct coastal impacts.
- The Texas Gulf Coast may see 2 to 4 inches of rain with isolated flash flooding, while the Mid-Atlantic and Southeast face a multi-day flood threat with some areas potentially receiving a month's worth of rain in days.
- Flood warnings are in effect in parts of Tennessee, Virginia, and North Carolina, with a Level 3 flood risk along the Virginia-North Carolina border and Level 2 risk extending through the Carolinas, Georgia, and Alabama.
- Heavy rainfall rates up to 2 inches per hour could overwhelm drainage systems in urban areas including Atlanta, Birmingham, and Charlotte, increasing the potential for dangerous flash flooding through Friday.
