Storms in Yonkers begin in a garage. Before the first flake, blades get hung and spreaders get filled, and the yard smells like diesel and cold steel at an hour with no traffic in it. H & C Truck Repair runs snow work out of that readiness — plowing driveways and lots, clearing walks and entryways, salting the grades where meltwater runs and refreezes. When the Hudson throws wet snow at Westchester, the trucks that keep going are the ones that were looked after back in October. Everything after that is steady passes until the pavement shows through.
