Storms are hitting Southern California with heavy rain that flooded roads, as millions are on alert for damaging winds on Tuesday. Meanwhile, in the North, millions are preparing for a winter storm.
Heavy thunderstorms in Southern California brought 1 to 3 inches of rain to the area, with the highest elevations seeing more than 3 inches.
Damaging winds gusted between 50 and 70 mph during the strongest thunderstorms. The highest wind gust reported was 81 mph in the hills above Malibu. This toppled trees and caused roof damage.
Issues popped up throughout the region, including flooded businesses in the Fairfax District, stranded drivers in Commerce, and a massive tree that fell on a car in Crestline, according to ABC News Los Angeles affiliate KABC.
A flood watch is in effect for the Santa Barbara and Los Angeles areas again Tuesday night due to the risk of flash flooding, debris flows and mudslides -- especially in burn scar areas.
Two more rounds of rain are expected across the Southern California area this week. The first is forecast to arrive Tuesday evening and continue overnight. The second is expected to arrive on Thursday morning to early afternoon.
This rain will be shorter-lived and less impactful than Monday’s event. Winds will be calmer, too. An additional 0.5 to 2 inches is possible through Thursday.
It will remain dry and sunny, with a warming trend through the weekend before more rain arrives Monday through Wednesday of next week.
In Sierra Nevada, heavy snow, strong winds and avalanche dangers have closed mountain roads and forced ski lodges to close as well.
The heavy snow will continue through the week, with snow accumulations of 4 to 8 feet through Friday.
Regions near the Canadian border from Montana to Michigan are bracing for a winter storm beginning Tuesday afternoon and lasting through Wednesday night.
Northeast Montana is already under a blizzard warning for gusts up to 55 mph, with up to 3 inches of snow expected Tuesday and Wednesday.
Winter storm warnings and watches are in effect from northern North Dakota through northern Michigan from Tuesday evening through Wednesday, as 4 to 8 inches of snow are expected to accumulate, along with wind gusts up to 35 mph.
Perhaps the most extreme portion of the event - another blizzard warning is in effect for the northwest side of Lake Superior, including Grand Marais and Two Harbors, Minnesota, where 10 to 18 inches of snow along with wind gusts up to 60 mph are possible from Tuesday night through Noon Thursday.
This line of snow will have the greatest impact on the Upper Midwest, but some snow is also possible Wednesday evening in New England, from upstate New York through Cape Cod. At least 2 to 5 inches of snow are possible from this quick, overnight snowmaker.
Severe thunderstorms with potential to produce a few tornadoes and damaging wind gusts are possible across parts of Illinois, Indiana, Kentucky and Ohio Thursday afternoon and evening.
