Freeze Warnings and Hard Freeze Warnings are in effect for the entire Phoenix metro area and most of central and southern Arizona again on Tuesday morning.
Keep the "4 p's" in mind whenever freezing temperatures are in the forecast. Those are PLANTS, PIPES, PETS and PEOPLE.
Cover any sensitive plants with a blanket, towel or sheet. Wrap any exposed pipes to prevent bursting and consider letting them drip slowly throughout the night. Bring your pets inside and bundle up yourselves throughout the overnight hours.
We are expecting widespread frost across the Valley. So be prepared to do some scraping of your car windshield if you leave it parked outside overnight.
