Two separate storms impacted the country this week, bringing heavy rainfall, flooding, power outages and heavy snowfall to portions of the northeastern and western United States.
Earlier in the week, heavy rain inundated areas across the I-95 corridor, blasting the region with strong winds as a storm system moved along the mid-Atlantic coast.
With chilly air locked in across Northern Virginia, eastern Pennsylvania and central Massachusetts, icy conditions followed.
Coastal flooding and flooded roadways occurred in portions of New Jersey, causing travel delays for commuters.
Very heavy rain unleashed flooding across Boston and much of southeast New England through the Tuesday evening rush hour.
As the week moved forward, heavy snowfall began to slam the Northeast region.
Snowfall amounts in New York state totalled to more than a foot of snow in some areas Wednesday night. Woodford, Vermont, also recorded 12.5 inches over the course of the storm.
Heavy, wet snow led to downed trees and power lines. Thousands of electric customers, particularly in Vermont, lost service due to the storm.
Meanwhile, interstates in upstate New York and northern New England were snow covered, making for treacherous travel conditions. New York Gov. Andrew Cuomo banned tractor-trailer travel on some interstates as a result of the storm, which also caused flooding problems on other New York highways.
Along the West Coast, one of the largest storms the region has seen in years packed a powerful punch, soaking the drought-stricken region with heavy rainfall, flooding, power outages and blizzard conditions in the Sierra Nevada range.
Disruptions to travel and outdoor activities persisted through Friday, impacting millions in the coastal Northwest. The storm will caused more flooding in poor-drainage areas and resulted in poor visibility for drivers along Interstate-5 and other major routes.
A major mud and debris flow occurred early Friday morning in Camarillo Springs, in the Springs burn area. The debris flow affected several homes on San Como Lane, according to the Los Angeles NWS Office.
At San Francisco, 9.34 inches of rain fell during December 2005, compared to an average of 4.03 inches for the month. As of Dec. 12, 2014, over 7 inches of rain fell this month, half of which fell during this event.
As of Friday, San Francisco saw 3.78 inches of rain from the storm. The highest rainfall storm total reported as of Friday was at Whiskeytown S.P. with a total of 14.8 inches.
While much of the Northwest and Central portions of California were impacted Thursday, the heavy rain pushed into southern California in the early morning hours Friday, brining travel problems and dangerous surf to the southern California coastline.
