Overview
- National Weather Service alerts in Southern California call for mountain and valley gusts up to 65 mph through Tuesday in some areas, with elevated risks of downed trees and power outages on saturated ground.
- After freezing rain and dense fog early Monday, an Arctic surge is driving temperatures sharply lower across the Northeast, with wind gusts frequently 40–60 mph and wind chills in the single digits or below zero on Tuesday.
- New England forecasters expect peak winds Tuesday late morning into afternoon, prompting high wind watches and advisories and raising the likelihood of tree damage, power interruptions and hazardous commutes.
- In the New York City area, a wind advisory runs through 1 p.m. Tuesday with gusts near 50 mph, as rain gives way to much colder air that could refreeze standing water overnight.
- Northern and Central California are briefly dry under offshore flow, but forecasters note model disagreement on New Year’s Eve showers and signal additional rain chances midweek, keeping tree‑fall and localized flooding concerns in play.
