(Updated 10:11 a.m.) The National Weather Service in New York now says a ‘potentially historic’ winter storm will impact Long Island and southern Connecticut late Monday through Tuesday evening, with snow accumulations of one to two feet likely and locally higher amounts possible. Expect winds of 25 to 35 mph with gusts up to 55 mph.
A blizzard watch remains in effect, effective from Monday afternoon through Tuesday evening, according to the National Weather Service — and officials say residents should stock up on essentials, including supplies that can be come critical in severe weather.
Heavy and blowing snow will reduce visibilities to one-quarter mile or less. The heaviest snowfall and strongest winds will occur overnight Monday into Tuesday.
Travel will be extremely dangerous with whiteout conditions possible; secondary and tertiary roads could become impassible, the NWS said. In addition, power outrages are possible as strong winds could down power lines and tree limbs.
National Weather Service meteorologist David Stark said a system is expected to develop on the mid-Atlantic coast Monday morning and move north offshore toward Long Island, bringing increased chances for snowfall Monday, with up to an inch possible by 6 p.m., just in time for the evening commute.
Temperatures will plummet Monday, Stark said.
“Enjoy today,” he said this morning. Temperatures are expected to reach a high of close to 40 degrees. As a colder air mass builds up tonight, temps are expected to plunge into the teens, and hover in the 20s Monday and Tuesday.
Residents should prepare in advance of a major storm. Stark said the time to prepare is Sunday. “Now is the time. Don’t wait until the last minute,” he said.
Primary concerns are loss of heat, power and telephone service and a shortage of supplies if storm conditions continue for more than a day. Residents should have available:
- Flashlight and extra batteries
- Battery-powered NOAA Weather Radio and portable radio to receive emergency information
- Extra food and water such as dried fruit, nuts and granola bars, and other food requiring no cooking or refrigeration.
- Extra prescription medicine
- Baby items such as diapers and formula
- First-aid supplies
- Heating fuel: refuel before you are empty; fuel carriers may not reach you for days after a winter storm
- Emergency heat source: fireplace, wood stove, space heater, properly ventilated to prevent a fire
- Fire extinguisher, smoke alarm; test smoke alarms once a month to ensure they work properly
- Extra pet food and warm shelter for pets
