There may be a pop-up thunderstorm Monday afternoon, with a high around 93.

Highs Tuesday are expected around 96, the hottest day of the week. The heat index value will make it feel around 101.

The heat poses a danger especially for the elderly, infirm and the very young, as well as for those who do not have air conditioning.

Pets are also susceptible to the heat. Cars with windows rolled up and no air condition heat up very fast.

A heat advisory means high temperatures and high humidity will combine to create a situation where heat illnesses are possible.

Protect yourself by drinking plenty of fluids and staying in an air-conditioned room.

Stay out of the sun and check up on relatives and neighbors.

Take extra precautions if you work outdoors or spend time outside.

Reschedule strenuous activity to early morning or evening.

Wear light and loose-fitting clothing and drink plenty of water.
