Pasadena Weathers 5 Inches of Rain Tuesday, Sunny Skies Return Today

A drenching cold winter storm has passed through Pasadena, bringing drier and breezy conditions Wednesday that are expected to last until Friday. But another storm is on the horizon and could arrive by the weekend.

Heavy rain pounded the area on Tuesday as yet another storm system thundered over the region, causing localized flooding and debris flows.  The powerful storm, which tapered off Tuesday afternoon, dumped more than 5 inches of rain in Pasadena, according to the National Weather Service.

The overnight downpours led to isolated flooding and debris flows Tuesday, making for a sloppy morning commute and warnings from local authorities for residents to stay off the roads if at all possible.

In San Marino, the Huntington Library, Art Museum, and Botanical Gardens announced that “due to saturated soils, the possibility of winds, and several fallen trees,” the gardens will be closed on Wednesday, although the facility’s galleries will remain open.

Dry weather will return Wednesday and Thursday, but more rain is likely to arrive this weekend, possibly as early as Friday. Saturday and Monday are most likely to see significant rainfall, according to the NWS.

In response to the seemingly relentless series of storms, President Joe Biden approved an emergency declaration for the entire state of California on Sunday and authorized the Federal Emergency Management Agency to coordinate disaster relief efforts and provide emergency resources.

Also Tuesday, the Internal Revenue Service announced that due to the storms and a resulting federal emergency declaration, Southern California residents and business owners will have until May 15 to file federal individual and business tax returns and make tax payments.

The one-month filing grace period is being offered to residents in areas designated by the Federal Emergency Management Agency as qualifying for tax relief due to storms — including individuals and households that reside or have a business in Los Angeles, Orange, Riverside and San Diego counties.

Temperatures will stay cool through the rest of the week, with most highs in the 60s and lows in the 40s, though overnight temperatures will drop into the 30s in the mountains and high desert.
