Residents are urged to stay hydrated and limit outdoor activity between noon and 5 p.m.
Showers and thunderstorms become more likely after midnight Tuesday into early Wednesday, especially along the Champlain Valley and I-89 corridor. New rainfall amounts will remain light, but isolated downpours and brief wind gusts could create slick roads during the early morning commute.
