SUBJECT: Change of Heat Advisory Thresholds across Upstate New

         York and Northern New England Effective June 1, 2018

 

Effective on or about June 1, 2018, four NWS offices (Albany,

NY; Binghamton, NY; Buffalo, NY; Burlington, VT), in

collaboration with the New York State Department of Health (NYS

DOH), will lower Heat Advisory criteria for all of New York for

the coming summer season.

 

Studies and research conducted by the NYS DOH 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 hours.

 

Also, effective on or about June 1, 2018, two NWS offices (Gray,

ME; Caribou, ME) will change Heat Advisory criteria to 95-99

degrees Fahrenheit occurring for two or more consecutive hours

from the previous two or more consecutive days.

 

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

heat-related illnesses and 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.
