Polo's remnants keep flash flood threat alive over Oklahoma and the Plains

What’s reported: Continuing coverage of former Hurricane Polo's remnants: the National Weather Service issued flash flood warnings for parts of Oklahoma as storms moved through the state late Wednesday into Thursday, Oct. 1. A flood watch covered part of the Panhandle plus southern and central Oklahoma, including the Oklahoma City metro. Storms carried an isolated tornado risk, possible 1-inch hail and 60-70 mph wind gusts. Earlier reporting noted flood watches stretched more than 1,200 miles across the center of the US, with heavy rain affecting parts of Texas, Kansas, Nebraska, Missouri, Iowa, Colorado and New Mexico as the remnants tracked northeast.

What it may mean for households: This is an update to the ongoing Polo remnant flooding, not a new storm. Flash flooding can develop quickly overnight even far from where a storm made landfall.

One practical step: If you are in a flood watch area, avoid driving through flooded roads and move to higher ground if water rises. Keep a charged phone and a battery or hand-crank radio for overnight alerts.

Southern California faces a lengthy, dangerous heat wave with fire danger

Single-source report — not independently confirmed.

What’s reported: According to ABC7 Los Angeles, Southern California's hot start to fall is expected to intensify over the weekend, with a potentially dangerous, lengthy heat wave. Many communities could see highs in the upper 90s and triple digits. An extreme heat watch for much of the region was expected to take effect Friday morning and last into the following Thursday night. Elevated fire danger was forecast for the valleys and Inland Empire, where highs could reach 102. Palm Springs was expected to hit about 100.

What it may mean for households: Extended heat raises risks of heat illness and wildfire, especially inland. This is a regional event affecting Southern California, not the whole country.

One practical step: Plan to stay in cool, air-conditioned spaces during peak afternoon hours, hydrate before you feel thirsty, and check on elderly neighbors and those without AC. Know heat-stroke warning signs and clear flammable brush near your home.
