Excessive rainfall and potential flooding are possible to occur again in multiple areas across the United States this weekend.
This is according to the National Weather Service (NWS), which warned of renewed severe weather from Sunday, September 11, until in the early part of next week.
In addition, thunderstorms could accompany the rainfall and result in the occurrence of widespread floodwaters.
The NWS said these weather hazards will coincide with tropical moisture before a cold front that can generate heavy rainfall and flash flooding as well, including in parts of Florida and the Mid-Atlantic region.
Furthermore, a low pressure area could also produce heavy rain in some areas of Wisconsin and Illinois.
Other states in the Northeast US and Southeast US could also experience renewed inclement weather.
US Meteorologists have considered that the wet weather serves as a relief to the drought-stricken regions of country, including the West, Southwest, and South US.
In recent months, the said regions have witnessed recurring spike in temperatures due to heat waves, causing the eruption of wildfires and prolonged dry conditions.
A widespread electricity crisis and rolling blackouts were also reported.
WPC Weather Forecast
On Saturday, September 10, the NWS' Weather Prediction Center (WPC) in College Park, Maryland, issued the detailed short-range forecast, which is valid until Tuesday, September 13.
In the weather outlook, the WPC mentions the following areas will receive a "Slight Risk" of excessive rainfall:
- Southern California
- Nevada
- Arizona
- Eastern Gulf Coast
- Central Appalachians
- Southern Mid-Atlantic
- Upper Great Lakes
The center noted that the Pacific Northwest will be an exemption to the forecast since the region is reportedly anticipated to experience elevated fire weather.

Excessive Rainfall and Thunderstorm
In previous weather events, the NWS and other US weather authorities, including the Storm Prediction Center (SPC) of the National Oceanic and Atmospheric Administration (NOAA), have forecasted thunderstorms are often accompanied by large hail and tornadoes.
The severe storms are in addition to rainfall, which can occur with or without warning, especially during afternoon and evening hours, as claimed by the authorities before.
Tropical Storm Kay
The US weather agency is also monitoring Tropical Storm Kay or Post-Tropical Cyclone Kay, which can still cause flooding in California and the Southwest.
Hovering over the Eastern Pacific basin, Kay was previously forecasted to bring torrential rain along the US-Mexico border.
According to CBSLA Meteorologist Markina Brown on Saturday, Kay is still expected to bring 2-4 inches of rain in Riverside County and its surrounding mountains.
Meanwhile, a substantial amount of rainfall could fall into Los Angeles County and the Ventura Valley area during this weekend, as cited by CBS News.
Drought Conditions Relief
The current weather conditions are almost similar to that of the August rains, which brought relief to Texas and other parts of the South US.
Last month, excessive rainfall also washed away most of areas suffering with drought conditions, including in Tippecanoe County, Indiana, according to the US Drought Monitor, as cited by the newspaper Lafayette Journal & Courier.
