Valentine's Day isn't supposed to be so frosty.

Sleet and freezing rain overnight added new levels of misery to yesterday's snowfall, bringing canceled classes and flights, and delayed trains and buses.

Here's a roundup of information and resources.

Traffic: Lots of spinout accidents were reported this morning. To see which area roads are having problems at the moment, check out traffic.com's map at http://go.philly.com/trafficmap. Put your cursor over the red, yellow or gray triangles and alerts will pop up.

Also, did you know you can actually get a look at major roads via PennDOT and NJDOT traffic cams? For PennDOT's, go to http://www.dot.state.pa.us/penndot/districts/district6.nsf/Cam_Frameset?OpenFrameSet. For NJDOT's, go to http://www.state.nj.us/transportation/traffic/cameras.

School closings. More than 800 closings and delays have been reported. For NBC10's list, go to http://go.philly.com/closings.

Air travel: Philadelphia International "Through about 11 o'clock about 50 percent of arrival and departures are canceled," says Mark Pesce, spokesman for Philadelphia International Airport. "We also have numerous delays." For flight information, go to http://www.phl.org or call 1-800-745-4283 (1-800-PHL-GATE). "The airport is operational," he said. "We've had crews working since yesterday keeping our airfield open, our roadway system, our sidewalks, everything that we do here." About 300 city employees help with airport snow removal, using 50 large pieces of equipment and assorted smaller ones to the airport's 25 million square feet of concrete, he said. "The airfield alone is 16 million square feet." (During better weather, those employees do other kind of maintenance.)

SEPTA: For the latest advisories about suspended service and delays, go to http://www.septa.org. As of 9:30 a.m., these notices were still posted: (1) Service temporarily suspended on R2 Marcus Hook/Wilmington between Newark and Churchman's Crossing due to a down tree. (2) Outbound delays of up to 10 minutes on the R5 Paoli Regional Rail line due to signal problems. (3) Paratransit service will only make work, medical and dialysis trips. (4) Service suspended on bus Route 35.

Electrical power: "The system is performing really well right now. We're not experiencing any major outages at this time due the weather," PECO spokesman Cameron Kline says. But PECO is concerned that more freezing rain could mean downed limbs and wires. Anyone experiencing an outage should call 1-800-841-4141 to report it.

PSEG in South Jersey reports no major outages, a spokeswoman said. Again, however, there are worries about further freezing rain.
