Burlington, Vermont – Hot, humid air and fast-moving thunderstorms are expected to sweep across Vermont Tuesday afternoon, just in time to snarl afternoon travel near Burlington and along I-89.

According to the National Weather Service in Burlington, the greatest risk for thunderstorms will occur between noon and 6 p.m. Tuesday, with an 80% chance of rain across Chittenden County.
