Statement as of 2:49 PM EST on February 01, 2011
… Ice Storm Warning in effect until 4 PM EST Wednesday…
… This replaces Winter Storm Warning…
The National Weather Service in Mount Holly has issued an Ice Storm Warning… which is in effect until 4 PM EST Wednesday. The Winter Storm Warning has been cancelled.
* Areas affected: west central New Jersey and much of southeast Pennsylvania just to the west and north of Philadelphia.
* Precipitation types: freezing rain.
* Accumulations: glaze accumulations of four to seven tenths of an inch are expected over most of this area by 10 am Wednesday. Already at 2 PM… there has been a report of one tenth inch of glaze from this mornings freezing rain and drizzle.
* Timing: spotty freezing drizzle will become a steady freezing rain late this evening and then occasionally heavy freezing rain between 3 am and 9am Wednesday before it ends as drizzle during midday Wednesday. There is a chance that the freezing rain will briefly mix with sleet for a time overnight.
* Impacts: travel will become treacherous later tonight through mid morning Wednesday on all untreated surfaces. Power outages are expected from breaking tree limbs and wires Wednesday morning. If glaze were to exceed three quarters of an inch… this would raise the potential for destructive widespread power outages. The Wednesday commute will be extremely difficult.
An Ice Storm Warning means severe winter weather conditions are expected or occurring. Significant amounts of ice accumulations will make travel dangerous or impossible. Travel is strongly discouraged. Commerce will likely be severely impacted. If you must travel… keep an extra flashlight… food… and water in your vehicle in case of an emergency. Ice accumulations and winds will likely lead to snapped power lines and falling tree branches that add to the danger.
