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.
