The National Weather Service has issued an excessive heat warning for Huron County and the surrounding areas.

The warning will be in effect from noon Friday until 8 p.m. Saturday.

Forecasters are calling for heat index values up to 107 due to temperatures in the mid 90s and dewpoints in the mid 70s. The highest heat index values will occur late afternoon into the early evening but little relief will occur overnight with low temperatures only dipping to the mid 70s to around 80 degrees.

The heat and humidity may cause heat stress during outdoor exertion or extended exposure.

Here is related information from the weather service:

Area residents who work or spend time outside should take extra precautions. When possible, reschedule strenuous activities to early morning or evening. Know the signs and symptoms of heat exhaustion and heat stroke. Wear light weight and loose fitting clothing when possible and drink plenty of water.

To reduce risk during outdoor work, the occupational safety and health administration recommends scheduling frequent rest breaks in shaded or air conditioned environments. Anyone overcome by heat should be moved to a cool and shaded location. Heat stroke is an emergency, call 9 1 1.

An excessive heat warning is issued when a prolonged period of dangerously hot weather will occur. The combination of high temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are likely. Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors.

Young children and pets should never be left unattended in vehicles under any circumstances. This is especially true during warm or hot weather when car interiors can reach lethal temperatures in a matter of minutes.

(ORIGINAL post)

Hot and humid conditions are expected Friday and Saturday. Forecasters say the heat index could hit 110 degrees or even higher.

Because of that, the National Weather Service has issued an excessive heat watch for Huron County and the surrounding areas. The watch will be in effect from noon Friday until 8 p.m. Saturday.

Heat indices ranging from around 105 to as high as 112 degrees will be possible both Friday and Saturday afternoons, the weather service reported.

The heat and humidity may cause heat stress during outdoor exertion or extended exposure.

An excessive heat watch is issued when a prolonged period of hot weather is expected. High temperatures and high humidity will combine to create a dangerous situation in which heat illnesses are possible.

PRECAUTIONS AND OUTLOOK

Residents will want to be sure to drink plenty of water, wear light clothing and take frequent breaks if strenuous activities cannot be avoided during the midday and afternoon hours to avoid suffering from heat-related illnesses, according to AccuWeather.

Taking a dip in your community's local swimming pool or heading to the beach is another great way to beat the heat, but be wary of thunderstorms that will erupt.

Barry, as a tropical rainstorm, will spread drenching showers and thunderstorms across the Ohio Valley and into the interior Northeast today.

East of the Appalachian Mountains, spotty thunderstorms will ignite in the afternoon with more numerous showers and thunderstorms to follow at night and into Thursday as Barry's moisture surges eastward.

"Given how much moisture will be in place, there is the potential for heavy rainfall with any showers or thunderstorms that do develop," according to AccuWeather Meteorologist Randy Adkins.

"Fortunately, downpours should be moving along rather briskly, so the threat for widespread flash flooding is low," he added.

A few issues can develop in low-lying and urban areas. Travelers, meanwhile, may encounter minor delays.

"Non-flooding downpours may not be a bad thing in areas where lawns are turning brown and gardens and crops are being stressed by hot weather and dry soil conditions that occasionally develop in July," according to AccuWeather Senior Meteorologist Alex Sosnowski.

While actual temperatures will be trimmed slightly as the downpours swing through, residents will not be treated to a reduction in the sweltering humidity. That will be the case even after the wet weather departs.

Instead, the door will swing wide open for more heat and high AccuWeather RealFeel® temperatures to engulf the Northeast to end the week.

AccuWeather meteorologists will be closely monitoring the threat for clusters of severe thunderstorms to erupt along the rim of this heat in the Upper Midwest and dive into a part of the Northeast.
