152 AM EST SUN FEB 1 2026
...COASTAL FLOOD ADVISORY REMAINS IN EFFECT FROM 8 AM THIS
MORNING TO 2 PM EST MONDAY...
* WHAT...ONE TO TWO FEET OF INUNDATION ABOVE GROUND LEVEL
EXPECTED IN LOW-LYING AREAS NEAR SHORELINES AND TIDAL
WATERWAYS (10.8 TO 12.7 FEET MEAN LOWER LOW WATER).
* WHERE...EASTERN ESSEX MA, SUFFOLK MA, EASTERN NORFOLK MA,
EASTERN PLYMOUTH MA, BARNSTABLE MA AND DUKES MA COUNTIES.
* WHEN...FROM 8 AM THIS MORNING TO 2 PM EST MONDAY.
* IMPACTS...SHALLOW POCKETS OF FLOODING LESS THAN ONE FOOT DEEP
AFFECTS THE LOWEST LYING AREAS ALONG THE COAST, INCLUDING
MORRISSEY BOULEVARD IN BOSTON. MOST ROADS REMAIN PASSABLE.
FLOODING UP TO ONE FOOT DEEP AFFECTS COASTAL ROADS ON THE
NORTH SHORE FROM SALEM TO GLOUCESTER AND NEWBURYPORT. ROUGH
SURF WILL CAUSE FLOODING ON SOME COASTAL ROADS AROUND THE TIME
OF HIGH TIDE DUE TO SPLASHOVER. ROADS REMAIN PASSABLE WITH
POCKETS OF SHALLOW FLOODING LESS THAN ONE FOOT DEEP. THIS
MAINLY AFFECTS LOW LYING AREAS AND ROADS NEAR EDGARTOWN
HARBOR, INCLUDING THE CHAPPY FERRY DOCK. SHALLOW FLOODING MAY
ALSO APPROACH FIVE CORNERS IN VINEYARD HAVEN.
* ADDITIONAL DETAILS...SUB-FREEZING TEMPERATURES AND COLD ROAD
SURFACES MAY ALLOW FOR SOME OF THE STORM SURGE TO FREEZE.
THIS WOULD RESULT IN PROLONGED ISSUES ON THOSE VULNERABLE ROADWAYS
AND ALSO DELAY DRAINAGE.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
IF TRAVEL IS REQUIRED, ALLOW EXTRA TIME AS SOME ROADS MAY BE
CLOSED. DO NOT DRIVE AROUND BARRICADES OR THROUGH WATER OF
UNKNOWN DEPTH. TAKE THE NECESSARY ACTIONS TO PROTECT FLOOD-PRONE
PROPERTY.
TIME OF HIGH TOTAL TIDES ARE APPROXIMATE TO THE NEAREST HOUR.
