PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE CARIBOU ME
1049 AM EDT THU AUG 12 2021

...NWS OFFICES SERVING NORTHERN NEW ENGLAND WILL CONDUCT AN
EXPERIMENT THIS FALL TO IMPROVE SERVICES RELATED TO THE 
FROST/FREEZE PROGRAM... 

THE NATIONAL WEATHER SERVICE’S (NWS) FROST/FREEZE PROGRAM CONSISTS
OF ISSUING FROST ADVISORIES, FREEZE WARNINGS OR HARD FREEZE 
WARNINGS WHEN COLD TEMPERATURES POTENTIALLY THREATEN TENDER 
VEGETATION AND CROPS DURING THE CLIMATOLOGICAL GROWING SEASON. THE
GROWING SEASON IS DEFINED BY THE PERIOD OF TIME BETWEEN THE 
MEDIAN DATE OF THE LAST SPRING FREEZE AND THE MEDIAN DATE OF THE 
FIRST FALL FREEZE. 

CURRENTLY, THE ENDING OF THE ISSUANCE OF FROST/FREEZE HEADLINES 
FOR A SEASON IS BASED ON THE OCCURRENCE OF A FREEZE IN ONE WEATHER
FORECAST ZONE OR TWO WEEKS AFTER THE MEDIAN FIRST FALL FREEZE 
DATE. THIS APPROACH WAS CONFUSING TO MANY USERS AS METEOROLOGICAL 
CONDITIONS OFTEN LED TO A PATCHWORK APPROACH OF ENDING THE GROWING
SEASON ACROSS MULTIPLE WEATHER FORECAST ZONES AND NWS OFFICES.

THE NORTHERN NEW ENGLAND NWS FORECAST OFFICES (BURLINGTON VT/GRAY
ME/CARIBOU ME)AND NWS ALBANY NY WILL CONDUCT AN EXPERIMENTAL 
PROGRAM SERVICE DURING THE FALL OF 2021. THE PURPOSE OF THIS 
EXPERIMENTAL PROGRAM IS TO STREAMLINE THE FROST/FREEZE PROGRAM FOR
SIMPLIFIED CUSTOMER USABILITY. 

THE END OF THE SEASONAL FROST/FREEZE PROGRAM WILL BE DETERMINED 
BY THE CLIMATOLOGICAL MEDIAN FIRST FALL FREEZE DATE. THIS MEANS 
THAT THESE NWS OFFICES WILL USE A FIXED DATE FOR CLIMATOLOGICALLY 
DEFINED AREAS, BOTH BASED ON 30-YEAR TEMPERATURE AVERAGES, TO END 
THE GROWING SEASON. 

DURING THE DEFINED GROWING SEASON, THE NWS WILL ISSUE FROST/FREEZE
HEADLINES AS NEEDED. ONCE THE DEFINED GROWING SEASON ENDS, 
FROST/FREEZE HEADLINES WILL NO LONGER BE ISSUED FOR THAT 
CLIMATOLOGICAL AREA. 

THE FOLLOWING ARE THE CLIMATOLOGICALLY DEFINED AREAS AND THEIR 
RESPECTIVE ENDING DATES OF THE GROWING SEASON IN NORTHERN MAINE.

SEPTEMBER 11TH: NORTH WOODS, INCLUDING NORTHWEST AROOSTOOK 
COUNTY, NORTHERN SOMERSET COUNTY, AND NORTHERN PISCATAQUIS COUNTY

SEPTEMBER 21ST: CENTRAL AND EASTERN MAINE, INCLUDING EASTERN 
AROOSTOOK COUNTY, SOUTHERN PISCATAQUIS COUNTY, NORTHERN AND 
CENTRAL PENOBSCOT COUNTY, AND NORTHERN WASHINGTON COUNTY

OCTOBER 11TH: DOWNEAST MAINE, INCLUDING SOUTHERN PENOBSCOT 
COUNTY, HANCOCK COUNTY AND CENTRAL AND COASTAL WASHINGTON COUNTY

AGAIN, OUR GOAL IS TO STREAMLINE THE FROST/FREEZE PROCESS BY 
USING DEFINED CLOSING DATES, WHICH SHOULD MAKE IT EASIER AND AID 
IN PLANNING DECISIONS FOR OUR USERS.
