...NWS AMARILLO TO CHANGE CRITERIA FOR HEAT ADVISORIES AND

EXCESSIVE HEAT WARNINGS...



Effective on May 1, 2024, the criteria for Heat Advisories for our

eastern counties in our County Warning Area will change to 105 

degrees for temperature and/or heat index values. Also, the 

criteria for Excessive Heat Warnings for our eastern counties in 

our County Warning Area will change to 110 degrees for temperature

and/or heat index values. This area will include Beaver County, 

Oklahoma as well as Lipscomb, Hemphill, Wheeler and Collingsworth 

counties in Texas. Criteria for our Heat Advisories and Excessive 

Heat Warnings in the rest of our area will remain unchanged and 

this will allow for all counties in the Texas and Oklahoma 

panhandles to have a consistent criteria for these heat products. 



The previous criteria for Heat Advisories in these eastern counties

was 110 degrees for temperature and/or heat index values; For 

Excessive Heat Warnings, this was 115 degrees for temperature 

and/or heat index values.



The changes to the Heat Advisory criteria and the Excessive Heat 

Warning criteria will better reflect heat impacts across the 

Oklahoma and Texas panhandles. In addition, these changes will 

improve collaboration and consistency with our neighboring NWS 

offices in Texas and Oklahoma.



As a reminder, a Heat Advisory is issued when the maximum 

temperature and/or heat index value is expected to reach criteria 

for one day or more, and/or when there is an elevated risk of 

heat related illnesses to those sensitive to the heat.



An Excessive Heat Warning is issued when the maximum temperature 

and/or heat index value is expected to reach criteria for one day 

more, and/or there is a significant risk of heat related illnesses

to all of the population.



Heat is the number one cause of weather related fatalities in the 

United States. Impacts from heat, including heat related illnesses

increase when the temperature exceeds 100 to 105 degrees.

Adjusting these criteria will help bring attention to potential 

for heat related illnesses across the combined panhandles. 



For questions or comments regarding this change, please contact 

Michael Gittinger, Meteorologist-in-Charge, or Joanne Culin,

Warning Coordination Meteorologist, at 806-335-1121.
