Tropical Storm Dexter, the fourth named system of the 2025 Atlantic hurricane season, formed late Sunday night well east of North Carolina. The system is now moving away from the U.S. East Coast, posing no land threat, but it signals a shift toward more frequent tropical development in the Atlantic.

The National Hurricane Center is monitoring three areas of possible tropical development. None are currently threats to the Gulf of Mexico.

With feels-like temperatures threatening to soar to 105 - 110 degrees, the National Weather Service has issued a heat advisory for Miami-Dade and Broward. The advisory is in effect from 11 a.m. to 7 p.m.

Miami had 60 days last year when the heat index was above 110 degrees F. This is considered extremely dangerous to people who do not have access to air conditioning and other ways to stay cooler than the outside temperature Heat is also a major cause of ER admissions during the hottest months.
