As Winter Storm Riley bears down on the Southern Tier, the Broome County Sheriff's Office has issued a 'No Unnecessary Travel Advisory.'

A No Unnecessary Travel Advisory is issued when severe weather and road conditions are present, but shouldn't be used as an excuse not to go to work. As a matter of fact, if you work, you should go to work unless your employer gives you other instructions. However, you're urged to use caution while driving because hazardous road conditions exist.

Broome County Sheriff David Harder reminds those who live in and work in Broome County that when the weather is less than favorable, as it is today, you should limit your travel if at all possible. If you do need to travel, you're encouraged to allow extra time to reach your destination and also to leave extra space between your vehicle and the vehicle in front of you.

Sheriff Harder also recommends that if you need to travel today, you should dress warmly and make sure to have a blanket in your car. You should also have at least half a tank of gas and take a fully charged cell phone with you in the event that you need to call for help.

Before you leave, make sure that you know alternate routes to get to where you're going in case your usual route isn't accessible. Also, if you need to slow down while driving, turn on your 4-way flashers.

The City of Binghamton reminds travelers that they're enforcing the winter alternate side of the street parking rules and has requested that all drivers move their vehicles off City streets and into parking lots and garages (you may have to pay a fee if you park in a lot) as soon as possible so that road crews can remove snow. Johnson City is asking drivers to do the same, however, parking in Johnson City municipal lots will be free all day Friday and Saturday.
