...WETTEST BACK-TO-BACK WATER YEARS IN DOWNTOWN LOS ANGELES
SINCE THE LATE 1800S!!!...

...SECOND-WETTEST BACK-TO-BACK WATER YEARS EVER RECORDED IN
DOWNTOWN LOS ANGELES SINCE OFFICIAL RECORDS BEGAN IN 1877...

In Downtown Los Angeles, the 2022-2023 water year was the 7th-
wettest on record, including a number of major winter storms, the
8th-wettest January, the 7th-wettest March, and the wettest August
on record fueled by the remnants of a rare tropical storm (Hilary).
The 2023-2024 water year continued to bring extreme weather to
southwestern California.

There were four major storm systems in the month of February
2024, including one that produced the 4th-wettest calendar day
in any February with 4.10 inches of rain. March also brought
above-normal rainfall to the region.

In Downtown Los Angeles, rainfall from this latest storm system
totaled 2.10 inches. Of that total, 0.12 inches fell on the 29th
before midnight, with 1.73 inches on the 30th, and 0.25 inches on
the 31st. The rainfall of 1.73 inches on the 30th set a calendar
day record, breaking the old record of 1.27 inches set in 1946.

Rainfall for this water year so far in Downtown Los Angeles
stands at 21.39 inches, more than 8 inches above the normal
rainfall to date, which is 13.00 inches. A water year begins on
October 1st and ends on September 30th of the following year.

The rainfall total for the 2022-2023 water year, which began
October 1st 2022 and ended September 30th 2023 was 31.07 inches,
which was the 7th wettest. The rainfall total for the 2023-2024
water year is already at 21.39 inches so far, with 6 months
remaining. The combined total for the last two water years is
now 52.46 inches and counting.

That is the second greatest rainfall total for two consecutive
water years since records in Downtown Los Angeles began in 1877. It
is also the most rain in consecutive water years since the water
years of 1888-1889 and 1889-1890, over 130 years ago. During those
two water years, which were the wettest back-to-back ones ever,
Downtown Los Angeles received 54.10 inches.

The following are the top five wettest back to back rain
seasons in Downtown Los Angeles:

1.  54.10" from Oct 1888 through Sep 1890.
2.  52.46" from Oct 2022 through Mar 2024 (with 6 months left).
3.  50.86" from Oct 1977 through Sep 1979
4.  50.44" from Oct 2004 through Sep 2006
5.  50.29" from Oct 1882 through Sep 1884
