Alerts in Effect
Severe Thunderstorm watchIssued at 7:54 p.m. EDT Saturday 20 September 2014
Conditions are favourable for the development of severe thunderstorms that may be capable of producing strong wind gusts and heavy rain. Thunderstorms extending from central Lake Huron across extreme Southwestern Ontario to Western Lake Erie are racing east and will affect Southwestern Ontario this evening. Torrential downpours giving 25 to 50 mm in an hour or less, and wind gusts of 90 to 100 km/h appear to be the main threats. Some of these thunderstorms also contain frequent lightning. There have been a few reports of wind gusts near 100 km/h from some of these thunderstorms over Lower Michigan and Indiana earlier this evening.Details
Fast moving water across a road can sweep a vehicle away. Strong wind gusts can toss loose objects, damage weak buildings, break branches off trees and overturn large vehicles. Remember, severe thunderstorms can produce tornadoes. 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.
