Heat Advisory in Effect as Rain Chances Increase Midweek
US · Published Aug 12, 2026
A strong ridge of high pressure is dominating the weather in West Palm Beach, Florida, leading to high temperatures and heat index values between 105°F and 110°F (40.5°C to 43.3°C).
While Tuesday remains mostly dry, Wednesday is expected to bring increased moisture and a better chance of scattered afternoon showers and thunderstorms, particularly as sea breezes collide across the interior.

Impact & Risks

The heat advisory poses risks for heat-related illnesses, especially for those spending extended periods outdoors. Vulnerable groups such as children, pets, and the elderly are particularly at risk. Scattered thunderstorms on Wednesday and Thursday may bring localized heavy rain and gusty winds, though not everyone will experience rainfall. The heat index values reaching up to 110°F (43.3°C) could exacerbate dehydration and heat exhaustion risks.
