PROVIDENCE, R.I. (AP) — A large part of Rhode Island is under a heat advisory as temperatures are expected to creep into the lower 90s.

The National Weather Service says Monday's temperatures will feel even hotter, with the heat index expected to hit the upper 90s or even 100.

The worst of it is expected in the afternoon and early evening. People are advised to drink plenty of fluids and stay out of the sun and in an air-conditioned environment if possible.

The Rhode Island Emergency Management Agency says several communities are operating cooling centers, including at some public libraries, senior centers and other locations.

The heat advisory extends to 8 p.m. in Washington County, eastern and western Kent County and northwest and southeast Providence County.
