Hurricane Polo Remnants Threaten Southwest and Central U.S. with Severe Flooding
Remnants of Hurricane Polo are expected to bring intense rainfall and a high risk of flooding to the southwestern and central United States this week. According to the NOAA Weather Prediction Center, New Mexico, Colorado, Texas, and Kansas face the highest impact risks, with some areas potentially seeing 10 to 20 centimeters of rain or more through Friday.
NOAA Issues Moderate Risk Warning for Five Consecutive Days
The NOAA Weather Prediction Center has forecast five straight days of adverse weather from Monday to Friday. The agency has designated this period as a moderate risk for excessive rainfall, which represents the second-highest level on a four-tier scale. This weather pattern is driven by the remnants of Polo interacting with a slow-moving front over the Great Plains, a combination that concentrates storms and moist air over the central states.
Texas and Colorado Face High-Impact Rainfall
In Texas, the most intense precipitation is expected between Wednesday and Thursday. These rains may be accompanied by severe storms, damaging gusts, and the potential for isolated tornadoes.
Colorado is also under significant threat, particularly in the southeastern portion of the state and around Colorado Springs. Because the remnants of Polo may interact with the Rocky Mountains and stall over the region, heavy rains are expected to persist through Thursday.
Flash Flood Risks in Drought-Stricken Zones
The National Weather Service has issued specific warnings for New Mexico, noting that urban areas, low-lying zones, streams, and regions recently affected by wildfires are especially vulnerable to river surges and flash floods. This risk is heightened in New Mexico, Colorado, Oklahoma, and Texas, where existing drought conditions mean the soil may saturate rapidly during intense bursts of precipitation.
Additional Moisture from Tropical Storm Rachel
The weather system may be further intensified toward the end of the week.
Regional Impact Summary
- Texas: Peak rain Wednesday-Thursday; focus on I-35 corridor, Austin, Dallas-Fort Worth, Waco, and Killeen.
- Colorado: Heavy rain through Thursday; focus on southeastern Colorado and Colorado Springs.
- New Mexico: High vulnerability for flash floods in burn scars and urban areas.
- Kansas & Oklahoma: General risk of excessive rainfall and flooding through Friday.
