Forecasters predicted Winter Storm Jonas would drop up to 12 inches of snow on New York City this weekend. As the storm intensified, so did projections of a more devastating blizzard.

The National Weather Service expects snowfall between 24 and 30 inches to fall in New York, western Long Island, and northern New Jersey by Sunday night. Jonas is already linked to at least 10 deaths, numerous car accidents, and power outages along the Eastern seaboard.

New York City Mayor Bill de Blasio issued a vehicle travel ban effective 2:30 p.m. Saturday afternoon effective until Sunday morning. De Blasio said the state will deploy "nearly 600 snow plows and 150,000 tons of road salt" when safe to do so.

All the threats associated with Jonas will be gone by the time the vehicle travel ban is lifted. While temperatures in affected areas will still be a few degrees above freezing, there will be little, if any, precipitation.

"The forecasts suggest that the snow will wrap up late tonight or in the very early hours of the morning," Washington D.C. Mayor Muriel Bowser said at a press conference. "But it doesn't make it any less dangerous. We expect continued high winds throughout the area which will continue to make the conditions and visibility very poor."

Like much of the east coast, Washington will see highs hover between the mid-to-high 30s on Sunday and Monday. Cold temperatures mean little relief from the mounds of snow that built up over the weekend. By Monday night, residents who endured Jonas will have to prepare for a round of rain showers.

Sporadic periods of rain will begin Tuesday morning, affecting cities ranging from Philadelphia to New York. The spat is expected to last through Tuesday night, but will make for dangerous driving conditions following feet of snow left over the weekend.
