SUBJECT:Change of Heat Advisory Criteria for Northeast New
Jersey, Long Island, Lower Hudson Valley, and Southern

The National Weather Service in New York, NY has lowered Heat
Advisory criteria for the upcoming summer.

Studies and research conducted by the Northeast Regional Heat
Collaborative show that emergency department visits and deaths
from heat increase significantly on days when the heat index
reaches 95 degrees F or higher.

Thus, the old threshold of 100-104 degrees F for two or more
consecutive hours has been lowered to 95-99 degrees F occurring
for two or more consecutive days, or any duration of heat index
100-104 degrees F.

There is no change of Heat Advisory criteria for New York City.

Excessive Heat Watch and Warning criteria (heat index 105 degrees
F or higher for two or more hours) remains unchanged.

It is expected that this change will alert people sooner to
impending heat threats and if acted upon, reduce the number of
emergency department visits.

No communication changes are required to receive heat
advisory, watch, or warning products. Only the triggering
threshold for heat advisories has been changed.
