PUBLIC INFORMATION STATEMENT
NATIONAL WEATHER SERVICE BOSTON/NORTON MA
1017 AM EDT THU OCT 20 2022

...NATIONAL WEATHER SERVICE-BOSTON WILL TEST NEW EXPERIMENTAL
WINTER STORM WARNING SNOWFALL CRITERIA FOR THIS SEASON...

THIS WINTER, THE NATIONAL WEATHER SERVICE FORECAST OFFICE IN
BOSTON/NORTON WILL SLIGHTLY MODIFY ITS WINTER STORM WARNING 
SNOWFALL CRITERIA. THIS CHANGE WILL AFFECT THE SLOPES OF THE 
BERKSHIRES AND WILL ALIGN SNOWFALL CRITERIA FOR WINTER STORM 
WARNINGS MORE CLOSELY WITH CLIMATOLOGICALLY-BASED IMPACTS. THERE 
WILL BE NO CHANGES TO WINTER WEATHER ADVISORY CRITERIA.

PREVIOUSLY, WARNING DECISIONS WERE BASED ON CONSIDERATION OF 
6 INCHES OCCURRING IN 12 HOURS AND THE EXPECTED IMPACTS. THE NEW 
CLIMATOLOGICALLY-BASED THRESHOLD IS CHANGING TO 7 INCHES FOR THE
EAST SLOPES OF THE BERKSHIRES, BUT WE WILL STILL TAKE INTO ACCOUNT
EXPECTED IMPACTS WHEN MAKING A WARNING DECISION.

THE ONLY ZONES IMPACTED ARE...

WESTERN FRANKLIN COUNTY (UGC ZONE MAZ002)... 7 INCHES. 
WESTERN HAMPSHIRE COUNTY (UGC ZONE MAZ008)... 7 INCHES
WESTERN HAMPDEN COUNTY (UCG ZONE MAZ009)... 7 INCHES
