With very warm temperatures and high humidity in the forecast, the National Weather Service has issued a heat advisory through Tuesday.

A heat advisory is issued when the combination of heat and humidity is expected to make it feel like it is 95 to 99 degrees for two or more consecutive days, or 100 to 104 degrees for any length of time.

Temperatures Monday and Tuesday will be about eight degrees above normal.

The record temperatures for this date are 96 degrees in Windsor Locks, 95 in Greenwich, 92 in Danbury, 91 in Bridgeport and 89 in New Haven.

The NWS is advising people to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check on relatives and neighbors.

Young children and pets should not be left unattended in vehicles.

Homes without air conditioning can be much hotter than outdoor temperatures.

Take extra precautions if you work or spend time outside.

When possible reschedule strenuous activities to early morning or evening.
