El Niño Watch, Wednesday 1/6/16

11:15 am – thunder and lightning just started here. The first round completely skipped the south coast, affecting both Big Sur Valley and Cambria, but not us.

In other news, Paso is not having a good day. One mobile home was blown upside down by high winds (tornado?) and another was hit by lightning, catching it on fire. Be safe and aware out there!

7:00 am – the storm woke me around 4:45 … Downpours, wind, and while I didn’t hear thunder or see lightning, others reported it. Fortunately, it has quieted down now. The rain total here, so far today, is .82″, 3.33″ for the month, and 16.99″ for the year.

This is yesterday, from Greg DeAlba, CT Supervisor at Willow Creek (looks to be near Alder, but can’t be certain). Annette Knight is running the loader. Go team!

“Today’s low pressure system will produce thunderstorms with
periods of moderate to heavy rain, gusty winds and possible
hail through tonight.

Snow levels with this storm system will range between 3,000
and 4,000 foot range North to South with another foot of new
snow for the high Sierra by Thursday morning. Total rainfall
with today’s system are expected to range between 1 and 2
inches.

Another low pressure will produce rain and fresh to strong
(25 to 31 mph) southwesterly winds on Thursday. Total rainfall
amounts with Thursday’s system should range between 0.50 and
0.75 of an inch.

Scattered rain showers are forecast on Friday into Saturday.

Clearing will develop Sunday into Monday as high pressure
briefly builds over California. Wet and unsettled weather is
forecast throughout the following week as the long awaited El
Nino type of storm pattern persist.” SLO Meterologist, John Lindsey.

Missed us here on the South Coast!

 

El Niño Journal, Thursday, Jan. 15,1998

1.6″ last night and it is still raining! Expected to last today through tonight, so I guess I’ll call Nina and tell her to forget Friday. Last night’s rain brings us up to 30.10″ to date.

My records indicate that end of January totals were:

1995- 36″ – Rd. Closed in all 3 directions in March.

1996 – 21″ – mild year

1997 – 65″ – road closed in lots of places, but no rain after Jan.

I’m going to call Kimball at 7:30 to see what we hear about road conditions and whether school is scheduled for today.

Per SLO tv, January is our wettest month, but here on the South Coast we have had some pretty heavy rains in March. 1995 an 1983 stand out. Both times the Hiway closed to the north for significant periods of time. March 1995, [rains] took out the Carmel River Bridge. With the help of the Army Corps of Engineers, a temporary Bailey Bridge, and a contractor who worked his men (including Kenny Comello) 12 hour days they were able to complete the bridge in 28 days.

I should probably go back and read that journal [March 1995] but I remember it vividly. Cambria was flooded – under about 3′ of water. The road in from the East, Nacimiento Fergusson, all bridges washed out and there was a slide on the south end of Highway One.

In March of 1983 I was still in Orange County [my last year as it turned out] but coming up to Esalen often. That year, the biggest slide in history occurred at Julia Pfeiffer Burns. That slide took 14 months to repair, and it’s been unstable ever since.

 

Rain total, Monterey County, 1/5/16 at 5:30 am

imageAt 5:30 am up here, the rain rate was a full 6″/HOUR. Now, at 10:00, it has picked up again. image

Flash Flood Watch

imageThe National Weather Service has issued flash flood watch for Santa Lucia Mountains, Los Padres National Forest, Southern Monterey Bay, and Big Sur Coast from late tonight through Tuesday morning. If you plan on traveling through FHL, call 831-386-2513 for up-to-date on info on road conditions.

i will wait on the 1998 excerpt, as this makes my third post today – all important, and necessary.

El Niño Report, Monday, 1/4/16

9:00 am – currently up to .37″, .20″ of that received in the last two hours. I hope to post an entry from my 1998 El Niño Journal this afternoon. I also have a photo album from February of 1998 I am going to try scanning. I have not been successful getting my VHS into DVD format, yet. I may have to find a professional.

Here is one forecast for this week:

“Total rainfall amounts for the week are expected to range
between 3 and 5 inches, with higher amounts in the Santa Lucia
Mountains.

[There will be] periods of moderate to heavy rain Tuesday morning. Rain will turn to scattered showers and the winds will shift out
of the northwest Tuesday afternoon and night. This system will
produce snow across the Sierra Nevada above 4,500 feet with a
foot of new snow possible above 6,000 feet.

Another moderately strong storm system will move into the
Central Coast on the heels of the Tuesday’s system with periods
of moderate to heavy rain and mountain snow during the day
Wednesday….Snow levels with this storm system will be a lower, ranging between 3,000 and 4,000 foot range North to South with another foot of new snow for the high Sierra by Thursday morning.

Rain will turn to scattered rain showers on Thursday into
Friday.

Clearing will develop Saturday into Sunday as high pressure
briefly builds over California. Wet and unsettled weather is
forecast throughout the following week as the long awaited El
Nino type of storm pattern persist.”

El Niño Journal, Monday 1/12/1998

1.3″ of rain today, .9″ last night for a total of 10″ so far this month. 10″ in 12 days. That’s considerable.

Going back through my records for the prior three years, I find that in January of 1995 we had 13.85″ by 1/12, none in 1996 and only 7.5″ in 1997 (although we had 44.45″ when we started January.) March of 1995 brought us 14.5″ in the first 12 days, so we are up there with the best of my prior recorded storms.

Storm Door to Open Next Week

imageReports aren’t quite consistent about when they will open, but some reports have it opening as early as Sunday afternoon. The biggest storm seems to be anticipated for Tuesday. Here is one graphic from Daniel Swain of Weather West:

My SLO forecaster writes:

“A major change in the weather pattern is underway as the
jet stream/storm track drops farther southward, increases
in speed and takes a more direct route across the Pacific
toward California.

These Upper-level winds will direct a series of low pressure
systems of varying strength into the Central Coast through
the first part of January, if not longer. Starting Sunday,
each day of the upcoming week is expected to receive
measurable precipitation. Total rainfall amounts for this
upcoming week are expected to range between 3 and 4 inches
with higher amounts in the Santa Lucia mountains.”

And here is one from NOAA showing the anticipated rainfall amounts:

El Niño Report, next 2-3 weeks

From Daniel Swain, of Westher West, where the full report can be found Here, comes this report:

“The area along of just north of the jet stream is a favorable position for storm development and intensification. Usually, California is located near the regional minimum of jet stream strength as it veers northward, but the imminent pattern shift will create a situation in which storms are much more likely to maintain their open-ocean strength or even strengthen as the approach California from the west. There is very strong multi-model support for an extended period (of at least 3 weeks, starting on Sunday) of greatly enhanced storminess and widespread precipitation throughout California.

A powerful and likely El Niño-influenced subtropical jet will develop over and south of California, creating a favorable condition for significant precipitation. (NCEP via tropicaltidbits.com)

I won’t even attempt to be specific regarding the details of individual storms at this point, since California’s favorable position to the north of a very strong subtropical jet leads to large instability in model solutions due to the much faster growth rate of storm systems than would typically be the case here (and, therefore, we should all expect forecasts to bounce around quite a bit in the coming days). But the screaming message, at this point, is that quite a few storms will affect California over the next 2-3 weeks. Not all of them will be strong, but some of them probably will be. Some may preferentially affect the northern part of the state; others will focus on the far southern region. But it seems very likely at this point that virtually all of California will significant, perhaps heavy, precipitation. Some of these systems may also bring strong winds and even some vigorous convective activity (thunderstorms), but these details are even harder to ascertain more than a few days in advance.”
