Slow-Moving Gulf and Southeast Storms Bring Local Flash-Flood Threat

Overview

• South-central Georgia saw 1 to 2.5 inch-per-hour rain near Valdosta late Tuesday, as a nearly stationary band raised a local flash-flood risk.
• Along the central to east-central Gulf Coast, heavy rain cores shifted east overnight Monday with 2 to 3+ inch-per-hour rates and pockets of 3 to 5 inches in a few hours.
• From southern Louisiana into southern Mississippi and southwest Alabama Monday afternoon, slow storms along a front produced hourly totals near 2 to 3+ inches and posed a flash-flood threat.
• Severe weather stayed isolated, with the Storm Prediction Center keeping watch odds to 20% in Florida on Tuesday and near 5% for the coastal Carolinas on Monday.
• Forecasters tie the flood risk to very moist air of 1.6 to 1.9 inches of precipitable water and weak winds that keep storms nearly fixed over the same neighborhoods.
