A powerful, slow-moving storm continues affecting parts of California on Monday, April 6, 2020, with significant mountain snow, heavy rain, and gusty winds. Up to 127 mm (5 inches) of rain fell in Santa Barbara County, causing localized flooding. A record rainfall of 28.4 mm (1.12 inches) was recorded in the Santa Barbara City, while Monterey saw 30.7 mm (1.21 inches) -- which above its average monthly rainfall. Showers and thunderstorms are also forecast for the Midwest in the following days.
According to the National Weather Service (NWS), an exceptionally deep upper-level low is predicted to linger near Southern California during the first half of the week, with the worst impacts to be felt on Monday.
Almost 60 cm (2 feet) of snow has fallen in the Sierra Nevada, with more expected through the week. Heavy snow continues to impact the San Gabriel and San Bernardo ranges as well.
"In addition, heavy rain is falling along the coastal range and in the valleys. The risk for flooding and flash flooding in some areas, particularly over burn scars, and runoff is possible in urbanized areas as well," said NSW.
