FLOODING ACROSS THE SOUTH

The primary concern over the next 48 to 72 hours will be heavy rainfall across the southern United States, especially from eastern Texas through Louisiana, Mississippi, and into Alabama.

A deep plume of moisture—originating from the central Pacific and enhanced by a strengthening El Niño—is feeding into this system. This setup will allow thunderstorms to produce prolonged and efficient rainfall, leading to widespread totals of 1 to 7 inches across parts of the region.

As a result, flooding is a significant concern, particularly in:

• Low-lying areas

• Poor drainage locations

• Small streams and creeks

Some areas could experience rapid runoff and flash flooding, especially where heavier bands of rain persist.

Severe Weather Component

Along the Gulf Coast, thunderstorms may also become strong enough to produce:

• Damaging wind gusts

• Isolated hail

While severe weather is a factor, the dominant threat remains heavy rainfall and flooding.

Bigger Picture

This event is part of a broader pattern that favors:

• Increased moisture transport into the South

• Repeated storm systems

• Continued heavy rain potential into the summer

Bottom Line

• Heavy rain from East TX → AL over the next 2–3 days

• Rainfall totals of 1 to 7 inches possible

• Flooding is the primary concern

• Some severe storms along the Gulf Coast (wind/hail)

• Pattern supports ongoing heavy rain risks

This is a high-impact rainfall event, where the combination of deep moisture and slow-moving storms will drive the potential for flooding across the region.
