Long Islanders are being urged to do whatever they can to beat the heat as temperatures again soar into the upper 90s for the second day in a row.

The National Weather Service issued a heat advisory from noon to 8 p.m. Thursday for all of Nassau and Suffolk counties except the South Fork.

“Hot temperatures and high humidity may cause heat illnesses to occur,” Upton-based NWS meteorologists said in the advisory. 

The advisory covers much of the tri-state area and comes after a prior heat advisory Monday.

The agency urged the public to 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, NWS added.

Anyone who works or has to spend time outside should take extra precautions, reschedule strenuous activities to early morning or evening if possible, and scheduling frequent
rest breaks in shaded or air conditioned environments if it’s not possible. NWS advised wearing lightweight and loose-fitting clothing when possible. 

Anyone who shows symptoms of heat exhaustion and heat stroke should be moved to a cool and shaded location and call 911.

Temperatures will cool off in Friday evening when strong, severe thunderstorms have the potential to drench the region for the second day in a row, potentially bringing up to 58 mph wind gusts, hail, and minor flooding, NWS said. The exact timing and intensity is not yet clear.

PSEG Long Island said as of Thursday morning it has restored service to the more than 10,000 customers that lost power in a fast-moving thunderstorm that affected parts of LI on Wednesday evening.
