Special Weather Statement
Special Weather Statement issued February 26 at 3:23AM EST by NWS Upton NY
Feb 26, 3:23 AM
→ Feb 26, 9:00 AM
Lightening winds and clearing skies are allowing temperatures to
drop quickly this morning. Much of the area will likely see
temperatures below freezing by sunrise if not already. These
freezing temperatures combined with overnight precipitation and
snowmelt have already caused areas of black ice. Black ice is
expected to become more widespread by sunrise.
Use caution if traveling this morning as black ice can make
conditions very slick and potentially hazardous. Leave extra room
between you and the car in front of you. Additionally,
pedestrians should use caution walking on any untreated surfaces.
