Florida Heat Wave and Storm Threat Prompt Safety Alerts

A heat dome over South Florida is driving temperatures around 91‑92 °F with heat‑index values reaching up to 105 °F in Miami and surrounding communities. The National Weather Service warned that prolonged outdoor exposure can be dangerous, advising residents and visitors to stay hydrated, wear light clothing, avoid parked vehicles, and seek shade.

On July 12, a storm system is expected to move into Central Florida, bringing a 60 % chance of thunderstorms between 3 p.m. and 6 p.m. in Orlando. The storms may produce gusty winds, frequent lightning and brief heavy rain. A plume of Saharan dust currently over the peninsula is reducing air quality, posing added risk for people with asthma or other respiratory conditions. Disney World guests were specifically cautioned to plan for the combined heat, storm, and dust conditions.

Authorities recommended that anyone caught outdoors during the storm window seek shelter, avoid open areas, and monitor local alerts. The dust is forecast to remain through the week, extending the elevated health risk.
