(CNN) Millions of people unaccustomed to heavy rain were drenched Tuesday by the remnants of Tropical Depression Rosa.

The National Weather Service in Phoenix said that city had its eighth-wettest day ever with 2.36 inches of rain.

Sandra Kotzambasis posted a video on Twitter that showed cars driving through north Phoenix with several inches of water covering the road.

"This is what I discovered as I tried to get to work," she wrote. " 'Lake Tatum,' just north of Shea (Boulevard). Needless to say, I am working from home today."

This is what I discovered as I tried to get to work. "Lake Tatum," just north of Shea. Needless to say, I am working from home today. Thank goodness @Fingerpainters allows flexibility. I know we need rain, but this is crazy! #azwx #HurricaneRosa #floating pic.twitter.com/Grt2DMqW7B — Sandra Kotzambasis (@Sandrakotz) October 2, 2018
