Triple Threat of Storms Unleashes Severe Flash Flood Risk Across the Southern US (Video)

The triple threat of storms that is bringing heavy rain to parts of the Southwest and Plains will interact with streaming moisture from the Gulf, bringing moderate to heavy rain across the southeast this weekend.

AccuWeather expert meteorologists say Gulf moisture will interact with a cold front slowly moving south across the Gulf Coast states and Southeast Friday into this weekend. This will lead to frequent downpours from portions of the Gulf Coast north into the southern mid-Atlantic, including Tennessee and the Carolinas. Additionally, remaining Pacific moisture to the west will bring a flood risk along a narrow corridor through Texas into Arkansas.

“The Gulf provides a vast supply of warm, humid air that, when interacting with a slow-moving front, can set the stage for heavy rainfall over multiple days,” said AccuWeather expert meteorologist Elizabeth Danco.

Triple Threat of Storms Bringing Life-Threatening Flash Flooding Risks to Colorado, Texas Hill Country

Heavy rain will shift into Colorado and the Plains Wednesday, including Texas Hill Country, bringing the risk for life-threatening flash flooding.

“The Texas Hill Country is always a flood prone region that has seen significant and deadly floods in recent years,” said Danco. “This storm will not carry the same extreme rainfall, but rainfall rates of 2-3 inches-per-hour can quickly turn dangerous, especially in the region’s diverse landscape.”

AccuWeather experts continue warning a triple threat of storms will bring heavy rain across the country throughout the week. Moisture from Pacific tropical cyclones Odalys and Polo are interacting with a storm system over the Rockies bringing moderate to heavy waves of rain across a region already soaked by the seasonal North American Monsoon.

Already in Albuquerque, more than 4-inches of rain have fallen over the past two weeks, as the city sets a September record for most rainfall.
