Southwest Flash Flood Warning and Coastal Rain - 10-19 to 10-21
Updated Mon Oct 19th 2026, 8:36am PDT

This week, we have some significant weather impacting our roadways. Heavy rain brings a risk of flash flooding in the Southwest on Monday. On the East Coast, a Nor’easter travels up the Mid-Atlantic, causing showers and potentially hazardous driving conditions through Tuesday. Meanwhile, California faces scattered showers as a low-pressure system moves along the coast. Stay safe and plan your travel accordingly. Let's break it down by region:

Southwest Flash Flooding Alert

Attention, drivers on I-10 and US-60 in Arizona and New Mexico! Monday's heavy rains bring a risk of flash flooding, particularly in southeastern Arizona and southwestern New Mexico. Be cautious on roads like AZ-77 and NM-89. These potential hazardous conditions may cause delays, so allow for extra travel time.

Mid-Atlantic and Northeast Coastal Showers

Folks traveling along the I-95 corridor from southern New Jersey through the Virginia Tidewater should prepare for rain showers through Tuesday. The Nor’easter is likely to create challenging conditions with strong winds affecting roads such as US-13 and US-17. Expect delays due to possible coastal flooding and road closures.

California Showers

Travelers along US-101 and CA-1, be aware of scattered showers moving through Northern, Central, and Southern California through Tuesday. These conditions could slow your commute and affect visibility, especially during heavy rainfall. Keep an eye on the forecast if you’re traveling via I-5.

Southeast Showers

If you're driving through Florida, especially along I-95 and I-75, expect scattered showers and thunderstorms through Tuesday. These weather conditions might cause slippery roads and reduced visibility, so drive safely and be prepared for possible delays.
