- Impacts – Swath of heavy snowfall from Boston through Down East Maine and Cape Cod. Strong winds as well producing localized blizzard conditions at times, especially for Down East Maine.
- Other Information – Very tight gradient in snowfall from the coast back inland. The slightest of differences in the track of the Low will mean significant differences in the snowfall amounts. For that reason, confidence in exact snowfall totals is still only moderate. Boston snowfall should begin to taper off later Sunday afternoon, Down East Maine not until later Sunday night but winds will continue to cause significant restrictions to visibility overnight Sunday into Monday morning.
Winter Storm Warning for Boston area.
... Winter Storm Warning remains in effect until 7 PM EST Sunday...
* locations... North Shore and southeast Massachusetts except for
Cape Cod and the islands.
* Hazard types... heavy snow and gusty winds.

this evening. The snow may fall heavily for a time tonight
into Sunday afternoon.
* Impacts... untreated roads and walkways will become snow
covered. Strong winds will develop after midnight and continue
through Sunday. This may result in poor visibilities and
perhaps near whiteout conditions for a time. In addition... the
initially wet snow combined with the wind could result in some
downed tree limbs and a few power outages.
* Winds... northwest 20 to 30 mph with gusts up to 45 mph.

inches in a 24 hour period. Travel will be slow at best on well
treated surfaces... and quite difficult on any unplowed or
