More snow is on the way for Warren County.

The Warren County School DIstrict has canceled school today, making the decision Wednesday afternoon.

On Wednesday, the National Weather Service in State College announced a lake-effect snow warning. Lake- effect snow bands will kick in today and continue through Friday night across the region.

Total snow accumulations could total between 6 and 15 inches with winds gusting as high as 50 mph. Whiteout conditions are expected at times and will make travel difficult and treacherous. The strong winds combined with the weight of snow on tree limbs may down power lines and could cause sporadic power outages. Areas of blowing snow could significantly reduce visibility. Gusty winds could bring down tree branches.

Ahead of anticipated winter weather across much of Pennsylvania tomorrow, the Pennsylvania Department of Transportation (PennDOT) is advising motorists to avoid unnecessary travel during the storm and to exercise caution when driving. Additionally, PennDOT will implement various speed and vehicle restrictions throughout the storm.

PennDOT crews will actively pre-treat roadways where necessary ahead of the storm to help prevent ice from forming a bond with the pavement during the early stages of a storm. However, salt does not resolve all risks, and drivers may encounter icy spots on the roadway. With freezing temperatures, roads that look wet may actually be icy, and extra caution is needed when approaching bridges and highway ramps where ice can form.

Restrictions are planned for certain vehicles during the storm, and will be communicated via variable message boards, the 511PA traveler information website and smartphone apps. Motorists can also sign up for personalized alerts on the website.

No commercial vehicles will be allowed on Interstate 90 starting today.

On roadways where vehicles are not restricted, commercial vehicle drivers in particular are encouraged to exercise caution in high winds. Drivers should ensure their loads are secure, reduce speeds, increase following distance, and use flashers if necessary.

Last winter in Pennsylvania, preliminary data shows that there were 151 crashes resulting in three fatalities and 55 injuries on snowy, slushy or ice-covered roadways where aggressive-driving behaviors such as speeding or making careless lane changes were factors.

Motorists should prepare for potential wintry weather by ensuring they have supplies in their cars before heading out: food, water, blankets, extra gloves and hats, cell phone charger, hand or foot warmers, windshield brush and scraper, and any specialized items like medications or baby and pet supplies.
