As temperatures were expected to soar on Monday, a heat advisory was issued by the National Weather Service for the entire Seacoast until 8 p.m.

Monday will be the worst of the heat with inland temperatures in the mid-90s. Dew points around 70 will push the heat index into the upper 90s, according to National Weather Service Meteorologist Hunter Tubbs.

It will be slightly cooler at the beaches.

Thunderstorms are not expected to develop on Monday.

High temperatures will remain in the 90s through Wednesday and then drop back into the 80s on Thursday and 70s through the Independence Day holiday weekend. While lasting several days this heat wave is not historical in nature, according to Tubbs.

"There's a fair number of years where we did have four days in a row" of highs in the 90s the most recent being in August, according to Tubbs.

The most consecutive days with temperatures in the 90s is nine, according to Tubbs.

Dover, Portsmouth and Rochester offer cooling centers for residents to get out of the heat.
