Updated at 2:41 p.m. – Environment Canada ends the thunderstorm watch for Chatham-Kent.
Environment Canada issued a severe thunderstorm watch for C-K at 10:22 a.m. – Conditions are favourable for the development of dangerous thunderstorms that may be capable of producing strong wind gusts and torential rain.
Southwestrn Ontario reamains in a stagnant weather pattern with sufficient moisture and unstable air to produce locally heavy thundrstorms. Clusters of thundrstorms will give several rounds of heavy thundrstorms and showers from late this morning into early this evening. Localizd torrential downpours will likely give in excess of 50 mm of rain in a short period of time.
Fast moving water across a road can sweep a vehicle away. Rapidly rising rivers and creeks can sweep away bridges, culverts, buildings, and people. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Intense lightning is likely with any storm that develops. Be prepared for severe weather. Take cover immediately, if threatening weather approaches. In Canada, lightning kills up to 10 people every year. Remember, when thunder roars, go indoors.
Emergency Management Ontario recommends that you take cover immediately, if threatening weather approaches.
Environment Canada meteorologists will update alerts as required, so stay tuned to your local media or Weatheradio. Email reports of severe weather to storm.ontario@ec.gc.ca or tweet with the hashtag #ONStorm.
