Extreme heat is expected across West Michigan on Monday, with conditions that could lead to thunderstorms in the afternoon.

The National Weather Service issued a Heat Advisory at 3:45 p.m. Sunday, effective through 8 p.m. Monday, June 23, for Clare, Isabella, Kent, Lake, Mecosta, Montcalm, Newaygo, and Osceola counties.

Heat index values could reach 102 with high humidity. Residents are urged to drink plenty of fluids, stay in air-conditioned spaces, avoid direct sunlight, and check on relatives and neighbors.

In addition to the heat, storms are possible in the northern half of Michigan’s Lower Peninsula on Monday afternoon. According to the Storm Prediction Center’s Sunday afternoon outlook, storms may merge quickly upon development, potentially producing strong to locally damaging wind gusts. Weak deep-layer shear will limit overall storm organization. Storms are expected between 2 p.m. and 11 p.m., with damaging winds as the primary hazard. The risk of hail and tornadoes remains low.
