Heat Advisory In Effect For Nassau County

A heat advisory has been issued for Nassau County for Sunday and Monday.

The advisory issued by the National Weather Service went into effect at 10 a.m. Sunday and will end at 8 p.m. Monday. It was already 85 degrees at Republic Airport in Farmingdale at 10 a.m.

Temperatures are expected to reach the low 90s Sunday and Monday, but with the humidity factored in, the heat index will climb to the mid-to-upper 90s.

The heat and humidity may cause heat stress during outdoor exertion or extended exposure, the NWS says.

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. In cases of heat stroke, call 911.
