Overview
- Dangerous heat continues across the Southeast and Florida with multiple Heat Advisories in place and heat‑index readings often at or above 100 to 110 degrees, creating high risk for heat illness and extra demand on utilities.
- Monsoonal moisture has shifted into the Southwest and Colorado, producing daily scattered thunderstorms and flash‑flood watches for burn areas such as the Aspen Acres zone where heavy rain can trigger ash and debris flows.
- The Phoenix metro faces an Extreme Heat Watch forecasted for early next week with highs expected near 108 to 112 degrees under the watch period.
- The National Hurricane Center downgraded Cristobal as it weakens over the Atlantic while Invest 92L carries a high (~80%) short‑term chance of development and Invest 94L has a moderate (roughly 30–50%) chance over the next several days.
- Some regions — parts of the Plains, Colorado and New England — will see brief relief from heat through a shift to cooler or drier air, but forecasts show heat returning in the Southwest and persistent daily storm threats where monsoon or Gulf moisture remains, raising risks for vulnerable people and local infrastructure.
