SUBJECT: Change of Heat Advisory thresholds for New England

         Effective immediately

 

Effective immediately, five NWS offices (Caribou, ME; Gray, ME;

Burlington, VT; Taunton, MA and Upton, NY), in collaboration

with the Northeast Regional Heat Collaborative, have lowered

Heat Advisory criteria for all of New England for the coming

summer season.

 

Studies and research conducted by the collaborative show that

emergency department visits and deaths from heat increase

significantly on days when the heat index reaches 95 degrees

Fahrenheit or higher.

 

Thus, the old threshold of 100-104 degrees Fahrenheit for two or

more consecutive hours has been lowered to 95-99 degrees

Fahrenheit occurring for two or more consecutive days, or any

duration of heat index 100-104 degrees Fahrenheit.

 

Excessive Heat Warning criteria (heat index 105 degrees

Fahrenheit 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 continue to receive

heat advisory/warning products. Only the triggering threshold

for heat advisories has been changed.
