A severe thunderstorm warning has reportedly been issued for parts of northern Ohio as a powerful line of storms threatens communities with heavy rainfall, damaging wind gusts, frequent lightning and potentially hazardous travel conditions. As storms move through, residents in the affected area are being advised to stay tuned to official National Weather Service alerts. During severe weather, conditions can change rapidly and communities outside the initial warning area should remain alert for other advisories.
Severe thunderstorms possible in northern Ohio
Storms that develop could bring a combination of heavy rain and gusty winds to northern Ohio.
Severe thunderstorms can generate wind gusts that are powerful enough to break trees, power lines and any outdoor objects that are not anchored. Heavy rain can also reduce visibility within minutes and make roads difficult to drive on.
If severe storms are passing through an area, residents should stay off the streets if possible.
Possible Flash Flooding Issues with Heavy Rainfall
Frequent thunderstorms or downpours can overload drainage systems and can be particularly problematic in urban areas.
Low-lying roads, underpasses, streams and places with poor drainage can become dangerous very quickly. Drivers should not try to cross a flooded roadway because you cannot tell how deep the water is or the condition of the road underneath it.
Even without a formal flood warning, a strong thunderstorm can cause localised flooding on streets.
Power Outages Possible from Damaging Winds
Thunderstorms sometimes produce strong, straight-line winds that can cause damage comparable to that of weaker tornadoes.
Falling trees and large branches could impact roads, homes, vehicles and electrical infrastructure. That opens the door to scattered or widespread power outages depending on the strength and coverage of the storms.
If there is time, residents should charge cell phones and other critical devices in advance of severe weather.
Lightning Is Still a Major Hazard
Lightning is another big hazard in thunderstorms.
If you hear thunder, go inside a large building rather than waiting for the rain to get heavy. Parks, sports fields, beaches and other open outdoor spaces are poorly protected.
The National Weather Service suggests that you wait at least half an hour after the final clap of thunder before heading outside.
Drivers may encounter hazardous conditions
In Northern Ohio, motorists may see sudden decreases in visibility during the heaviest rainfall.
Hydroplaning can occur in standing water and roads may be blocked by fallen trees or power lines after high winds. Drivers are advised to slow down, increase following distance and avoid flooded streets.
If you must travel during an active severe thunderstorm warning, consider postponing your trip until conditions improve if possible.
Residents Must Know Difference Between Watch and Warning
A severe thunderstorm watch means conditions are favourable for severe storms to develop over a larger area.
Warnings are more urgent . They are issued when radar detects severe weather or trained observers report severe weather and that weather is threatening a specific area .
If you are caught in a warning you should take shelter inside and stay away from windows until the storm has passed.
