The National Weather Service forecasts an abnormally long stretch of bitter cold hitting central Pennsylvania late this week into next week. Pennsylvania American Water advises keeping thermostats steady, letting faucets trickle, opening sink cabinets and insulating vulnerable lines to prevent frozen pipes. If pipes freeze, homeowners should shut off the main valve, thaw with controlled heat such as a hair dryer and reopen water slowly while checking for leaks. Pennsylvania’s Libre’s Law limits tethering dogs outdoors to 30 minutes when temperatures are below 32°F and sets standards for lead length, collar type and access to drinkable water. Veterinary experts warn of frostbite and hypothermia risks for pets and of lethal ethylene glycol in antifreeze, recommending booties, paw balms, weather-appropriate clothing and unfrozen water supplies.
