The National Weather Service in Shreveport has issued its first “Excessive Heat Warning” of the summer, which will be effective through 7 p.m. Monday.
This is an upgrade from the previous heat advisory. It includes Columbia, Lafayette, Nevada, Ouachita and Union counties, and adjacent North Louisiana parishes.
An upper level heat ridge will remain in place across the Four State Region through the early part of the work week.
High temperatures will continue to approach triple digits with heat index values reaching or exceeding 110 degrees. Expect limited relief overnight with lows into the upper 70s to around 80 degrees.
High heat index readings will increase the risk of heat-related illnesses, including heat stroke which can be deadly.
The weather service advises the public to take extra precautions if you work or spend time outside. When possible, reschedule strenuous activities to early morning or evening.
Know the signs and symptoms of heat exhaustion and heat stroke, such as a sudden lack of perspiration.
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 911.
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.
The intense heat will continue into Tuesday across the entire Four State Region with ambient temperatures in the upper 90s to near 100 degrees with heat indices nearing 110 degrees in a few locations.
Showers and thunderstorms will increase Wednesday across the region in response to the arrival of a cold front. This front will help to lower temperatures and humidity values through the end of the upcoming work week.
