The city of Philadelphia has declared a snow emergency effective at 9 p.m. Sunday, anticipating significant snowfall and dangerously cold temperatures in the coming days. Reports indicate that the region has already experienced snowfall, with totals reaching up to 6 inches in certain areas, and residents are being advised to be cautious of slippery road conditions. As arctic air moves in, forecasters warn of potential below-freezing temperatures and gusty winds. The Philadelphia Parking Authority is offering a special $5 garage rate to assist residents during the snow emergency. Community outreach groups are mobilizing to support the homeless population, urging those unsheltered to seek resources provided by the city as a Code Blue goes into effect. Officials from the city and PennDOT are closely monitoring the situation and are prepared to keep roads passable during the winter storm.
