If you’re planning on spending the 4th of July outdoors, make sure you bring lots of water and take frequent shade breaks today.

The National Weather Service has issued a heat advisory for coastal, metro and inland Palm Beach County until 8 p.m.

Temperatures will be in the high 80s / low 90s throughout Independence Day, but peak heat index values (feels-like temperatures) will range between 105 and 110 degrees in the afternoon. The NWS is warning that the high temperatures and humidity are a threat for heat illnesses.

It’s not likely any of those afternoon storms will pop up today to cool us off either. It’s expected to be a rain-free day before more summer-like storms appear Friday and through the weekend.

If you’re outside today, follow these guidelines:

• Drink plenty of fluids.

• Wear lightweight and loose fitting clothing.

• Try to limit strenuous activities to the evening.

• Take action when you see symptoms of heat exhaustion and heat stroke.

• Check up on relatives and neighbors.
