The hot temperatures, along with continuing gusty winds through the week will lead to an increased risk of fire danger.

Officials suggest drinking plenty of fluids and checking up on relatives and neighbors.

Cooler conditions are expected on Saturday, with temperatures dropping significantly by Sunday.

A storm system may even make its way into the region Sunday night and bring showers into Monday morning.
