Special Weather Statement
Dry and breezy conditions expected today. The combination of
afternoon RH values around 30 to 40 percent and a southwesterly
flow increasing to 20 to 25 mph gusts will result in an elevated

including machinery, cigarettes and matches. Any fires that ignite
will have the potential to spread quickly.
The forecast considers meteorological, fuel and land conditions
and has been developed in coordination with state fire and land
management officials.

**Black Ice and Blowing Snow Tonight**
Black ice will be possible across the region tonight, especially
on any untreated surfaces. Gusty winds may also result in
localized reduced visibilities due to blowing snow through
Tuesday morning. Take caution if traveling, especially on the
Tuesday morning commute.
From: Feb 23, 2026 21:53
Until: Feb 24, 2026 15:00
Blizzard Warning

blowing snow. The strong winds and weight of snow on tree limbs
may down power lines and could cause sporadic power outages.
Whiteout conditions are expected and will make travel treacherous
and potentially life-threatening. Plan on slippery road
conditions. Areas of blowing snow could significantly reduce
visibility. The hazardous conditions could impact the Monday
evening and Tuesday morning commutes. Strong winds could cause
tree damage.

vulnerable areas near the waterfront and shoreline.
* WHERE...Southern Middlesex and Southern New London Counties.
* WHEN...From 11 PM this evening to 5 AM EST Monday.
* IMPACTS...Widespread minor coastal flooding is expected in the
most vulnerable locations near the waterfront and shoreline.
Expect up to 1 1/2 ft of inundation above ground level in low
lying, vulnerable areas. Some roads and low lying property
including parking lots, parks, lawns and homes/businesses with
basements near the waterfront will experience shallow flooding.
* ADDITIONAL DETAILS...This water level forecast has been leaned
towards a high end scenario, providing a margin of safety. It is
highly dependent on timing of windshift from northeast to north
storm force winds with respect to the time of high tide. If
shift to northerly winds occurs earlier than time of high tide,
water levels will fall to the low end or even below the
forecast range.

Special Weather Statement
***Multiple Bands of Heavy Snow to Impact the Area Overnight***
Bands of heavy snow will move across the area through the overnight
as low pressure rapidly intensifies to the south. Some of these
bands will produce 2 to 3 inches per hour rates. However, in
between bands, snowfall rates may drop off to about an inch per
hour.
Farther to the west, across western portions of the Lower Hudson
Valley and interior portions of northeast New Jersey there will
be a sharp back edge to the heavy snow and some uncertainty as to
how far these bands get. This could impact snowfall totals across
this area.
Additionally, winds will become a factor as the night progresses.
Blizzard conditions are expected and will make travel treacherous
and potentially life-threatening.
