February was the wettest month in downtown Los Angeles since 1998. With over 12 inches of rain drenching the city, it was the fourth-wettest February — and the seventh-wettest month overall — in the city’s nearly 150-year recorded history.

You can feel the saturation in the soil, Park Williams, a professor and expert in water and drought, said in a phone interview last week as he was walking across the grass at the University of California, Los Angeles.

An astonishing 11 inches of rain fell in just two days in early February across the U.C.L.A. campus, which is tucked closer to the base of the Santa Monica Mountains than the downtown area. According to Dr. Williams’s calculations, that meant 1.1 billion pounds of water fell over the campus those two days.

The downtown area, a little farther east, received seven inches during that same period of time. A normal amount for the entire month of February is just under five inches for U.C.L.A. and four in downtown.
