Storms with high winds struck in October. A max wind gust of 48 mph was recorded on the 17th. This tied the previous peak wind gust ever recorded on my instrument back in the ’92-’93 storm season.
Snow fell and stuck at the top of HCR on the 21st after a surprise storm brought a night of thunder, lightning, wind, rain, hail, sleet, and snow. A total of 1.13 inches of rain fell in the storm.
Storms produced stiff winds similar to November, knocking more trees down in HTC.
Lots and lots of rain. HTC Creek plus other creeks are now flowing across Temescal Canyon road.
Heavy rain continued. This year is now in 3rd place for the wettest year in HCR since 1990. We have a ways to go to reach the 35.09” of 1992-93. As of 3/1/05, Lake Elsinore was seven inches away from overflowing into Temescal Canyon Wash. If that happens, the roads at the bottom of the hill will really get messy.
The “faucet” turned off this month giving us a chance to dry out. Looks like the rainy season may be coming to an abrupt close.
An unusually strong storm, for April, dumped 0.95” of rain in the morning hours of the 28th.
Although the season’s total rainfall in L.A. was the second wettest in history, it was HCR’s third wettest, coming in at 29.49 inches.
Summer monsoon season started. Severe thunderstorms were all around but not quite on top of HCR. Warmest night since 1990, 76 °F, was recorded.
The 20th of the month brought the most spectacular, non-stop lightning show seen in my lifetime. Starting with a beautiful rainbow at sunset with forks of lightning seen in the background, the lightning didn’t stop until mid-morning the following day. A brief heavy downpour brought the monthly rainfall total to about a quarter of an inch.
More thunderstorms formed in the latest early fall cutoff low. Most of the activity was toward L.A.
Amazing monsoon flow occurred this month. Record high and record nighttime temperatures were set. Thunderstorms were plentiful and dropped .15” of rain. Although I recorded a high of 111.6 on my Oregon Scientific instrument, I believe I was about 2 degrees too warm since my home made radiation shield is not as good as it should be. My new Davis instrument runs about 2 degrees cooler - so I am logging 109.6 as my new high temp for that day.
