GRAY — The National Weather Service has issued a heat advisory for much of Maine warning that the combination of high temperatures and high humidity will make it feel like 100 degrees in places.

Today’s advisory includes all of coastal Maine and inland areas that cover the population centers of Portland, Lewiston, Augusta and Bangor.

Temperatures are expected to rise into the 90s across most of the state – and into the upper 90s in some inland locations – marking the fifth consecutive day of 90-plus temperatures.

The weather service says the high heat and duration of the heat wave is making for uncomfortable and potentially dangerous conditions, especially in hot buildings without air conditioning or proper ventilation.
