Flash Flooding in the South:
In the southern part of the country, more than 10 million people are on alert for possible floods. The flood watches cover a vast area from eastern Texas to northern Alabama until Wednesday afternoon. Drought-stricken regions may see over 5 inches of rainfall, causing dry soil to overflow and leading to additional flooding. Texas, including San Antonio, has already experienced flash flooding due to heavy rain.
Travel Threat in the Central US:
Parts of the central US are facing a travel threat due to freezing rain and scattered snowfall. Roads might become icy and power outages could occur on Tuesday. The Midwest to the interior Northeast is particularly at risk. Air travel may also be disrupted by icy weather, as Monday already saw delays and cancellations at airports such as Chicago’s O’Hare International Airport and St. Louis Lambert International Airport.
California Flooding and Rescues:
Winter storms continue to impact the West, with California facing flooding issues. San Diego is dealing with the aftermath of heavy rain that sent fast-moving water through the streets, prompting hundreds of rescues. The mayor has declared a state of emergency, and cleanup efforts are underway. Temporary shelters have been set up for those displaced or homeless.
Serious Flash Flood Threat in the South:
The South is facing a serious threat of flash floods due to continuous warm, moist air. The Gulf of Mexico is contributing to increased moisture, raising the flood risk. Tuesday and Wednesday are expected to be critical days, especially for Louisiana and Mississippi, with a Level 3 out of 4 risk of excessive rainfall. Widespread rainfall of 4 to 6 inches is likely, posing a significant risk to drought-stricken areas where the dry and hard ground hinders water absorption.
Persistent Rain in the South:
Even after Wednesday, steady rounds of rain will persist throughout the week in parts of the South. By Friday and Saturday, the wet weather will expand across the East, bringing dreary conditions. Around 1 to 2 inches of rain are expected from the central Appalachians through New England during this time.
Icy Roads Creating Travel Woes:
Over 50 million people are under winter weather alerts from Kansas to New England. A combination of moisture and cold air is causing icy roads, with the potential for accidents and power outages. The accumulation of ice on roads and sidewalks poses a significant threat. National Weather Service offices are advising against unnecessary travel in hazardous conditions.
The United States is currently grappling with a combination of floods in the South and icy conditions in the central and northern regions. Residents are urged to stay informed about weather updates and take necessary precautions to ensure safety during these challenging conditions.
