Storm and Road Conditions, 3/21/18

7:45 am – This is both odd and confusing, but if CT moved closure from Salmon Creek to Ragged Point, something happened down south. Nothing noted to the north, so ??? Rain continues, and due to increase later. Hope to take 1 north this am around 9, so will report  back with what I find out.

7:41 AM 1 [1] SR1 CLOSED AT RAGGED POINT DUE TO A SLIDE,UNK DURATION FOR CLOSURE

This from Susana Cruz, CT PIO:

”Status: New
Location: District 5, SR 1, San Luis Obispo
Description: Due to rocks falling onto the roadway
Impact: Route closed at Ragged Point
Estimated Time of Reopening: Unknown”

Also, Santa Rosa Creek Rd. in Cambria closed last night near 46 by a 100’ wide, 2’ deep slide. Unknown eta for clearance.

First Day of Spring, and Storm Report, 3/20/18

5:30 pm – Chalk Peak is up to almost 1/2 and inch and Mining Ridge has almost reached 1” and the heavy stuff is still to come.

3:30 pm –  From NWS: “SUMMARY…HEAVY RAINS TO BEGIN OVERSPREADING THE CENTRAL/SOUTHERN CA COASTAL RANGES LATE THIS AFTERNOON AND THROUGH THIS EVENING AS ATMOSPHERIC RIVER CONDITIONS COMMENCE. SOME RUNOFF CONCERNS WILL BE POSSIBLE ALONG WITH ISOLATED FLASH FLOODING CONCERNS NEAR ANY BURN SCAR AREA.

So far, no reported problems in Big Sur, but the front just hit my place at 3:37 pm and there has been a significant increase in the rate of rain that is now falling.

7E0F076A-F3B3-455C-8D35-DED08123B2A6

3 pm – Regional radars continue to show rain increasing in coverage along the Central Coast this afternoon. Rain rates expected to increase this evening & overnight there, greatest rain totals in the coastal mountains.

758CA5AA-4C1F-4911-A649-5B7CD1D44C18

Noon: Mandatory Evacuations in red, recommended in yellow, issued today at noon.

790DCDEA-D133-4002-AB11-1A5B78F4C9FF

Noon: NOAA issued the following map today, but it applies to Wednesday through Thursday. Note, all of Mo Co appears to be in the high risk area:

B4AD7B08-F99C-4D05-910B-3DE94BB42467

9:30 Changed the header to a happier, spring photo to celebrate the vernal equinox. Of course, the big story today is the storm. The rain already started in town, around 7:30 am. Here, it has been drizzle only and the precipitation map is showing nothing for Chalk Peak, yet. It is coming.

“The greatest rainfall totals will be along the coastal ranges of the Santa Lucia Mountains where 3.00″ to 6.00″ will be likely with isolated amounts approaching 10.00″. (Previously expected for Chalk Peak and Mining Ridge.) With this, the greatest potential for small stream flooding and mudslides, rock slides and debris flows will be along the Big Sur coast.”

I will be reporting throughout the day as needed, particularly with regard to any reports I get about the road.

Storm update, 3/19/18

I thought Santa Barbara was in the bull’s eye, but it looks like we might be, starting tomorrow morning. From NOAA: (NOTE THE MOST IMPORTANT INFO FOR US IS THE LAST PARAGRAPH.)

“Models have remained rather consistent bringing the first moisture push to the region early Tuesday. Light to moderate rain is on track to develop Tuesday morning along the Big Sur Coast and then spread northward through the day. As light to moderate rain spreads north, moderate to heavy rain is expected to develop over
the Big Sur Coast/Santa Lucias Tuesday afternoon as low level increases and higher PWATs slam into 5k ft peaks. The moderate to heavy rain will likely cause some minor hydro issues along the Big Sur Coast with creek rises, ponding and possible low end flooding at this time. The lower confidence part of the forecast is where this intense plume of moisture sets up. Current forecast/model guidance keeps it at Big Sur, but if it shifts just 30-50 miles north it could be a different ballgame and Santa Cruz Mts could
get dumped on. That solution is less likely, but still wanted to mention it. Winds will also increase out of the south Tuesday into Wednesday. Winds will be strongest along the coast and higher coastal peaks with gusts 30-40 mph….

Heaviest rainfall is still slated for Tuesday morning throughThursday morning with pulses of moisture. Only minor tweaks to previous rainfall, but Big Sur Coast will see the most. Rainfall amounts are anticipated to range from 0.75″ to 1.50″ in most urban
areas with 1.00″ to 3.00″ in the North Bay and Santa Cruz Mountains and 2.00″ to 5.00″ in the Santa Lucia Mountains above the Big Sur Coast. Could see isolated amounts upwards of 8.00-10.00″ along the southwest facing coastal slopes of Monterey County (Mining Ridge/Chalk Peak).” (Ed. Note: that’s from Big Creek south to the Chimney Slide areas, so look for potential problems at the usual culprits:Cow Cliffs, Paul’s Slide and Chimney Slide. I cannot even guess what will happen at Mud Creek.)

 

Misc notes, 3/19/18

1. Today’s Cal Trans update was a repeat of the last few months, nothing has changed. Paul’s Slide is still one way controlled, Mud Creek is still closed. They sent a new photo taken on Friday at Paul’s Slide. Note all the nice new asphalt … just in time for the floods of the next few days.

2. There will not be a Tourist Tuesday tomorrow, as I have cleared the deck for storm watch for the next few days so that I can keep an eye on the storm & the road and report on anything you need to know. Perhaps next week. Mandatory & Voluntary Evacuations have been issued for the burn areas of the Thomas Fire in Santa Barbara. As of Monday night, they appear to be in the bull’s eye, but SLO and South Coast Big Sur will be getting hit hard as well. Road closure is enevitable…only question is for how long. Even the where is pretty well known. Stay tuned and stay safe.

Atmospheric River coming, 3/19/18

This does not bode well for any of us, but particularly for the fire areas of Santa Barbara. Time to get prepared. The rest of us will be slammed here on the Central and Southern Coasts, but oh, man, Santa Barbara County, my thoughts and prayers are with you. Please pack up and get out today.

15E36A9B-6010-4928-A9F3-DD3CC3228EB3

By Daniel Swain of Weather West: “Upcoming storm event actually concerns me more than Jan 9 event, which resulted in the devastating #Montecito debris flow event downstream of #ThomasFire burn scar. It will be prolonged, and likely intense. Those in evacuation zones should leave Monday.#SantaBarbara #CAwx #CAfire”

From NWS-LA: “A significant storm system still on track to bring rain to #SoCal Tue-Thu! Flash flooding possible in many areas, flooding& debris flows possible near recent burn areas. #CAstorm #Cawx”

49BA59F3-D29E-4C29-AC9E-EE04B3691AE6

 

And from John Lindsey’s (SLO report): “At this time, total rainfall amounts of between 4 and 6 inches with higher amounts in the Santa Lucia Mountains is expected. Between 4 and 8 inches of rain could fall in the burn areas of Santa Barbara & Ventura counties
on Tuesday into Thursday. This potential situation will be to be monitored closely. snow levels will remain above 7,500 feet.”

Again, Daniel Swain: “”5σ PW anomalies” translates to “huge amount of water vapor in the column of air above your head, of a magnitude that is historically rare.” This is why there is so much concern regarding #ThomasFire burn scar in #SantaBarbara and #Ventura. #AtmosphericRiver

Note the following predictions are for Tuesday, Wednesday, and Thursday, posted in order. Mon Dieu!

BSMAAC Meeting 3/23/18 – Agenda and prior meeting notes

Yes, it looks like I am missing the first page of the minutes. I am sorry, I am sure it is a simple fix, but my head is full of cotton. I have the cold from hell and am in bed. I will fix it as soon as my head is clear. Trying the elderberry tincture and that stuff is nasty. If it works, will fix this.

Next week’s weather system

Remember this forecast for the next storm?

This is what NOAA said this afternoon: “…the national WPC suggests
local amounts of 3-5 inches over the highest Big Sur peaks with
slightly less over the Santa Cruz mountains,”

Sunday should be clear, a good time for any additional preparation you may have forgotten. Remember, all that rain on our mountains translates to water rolling downhill toward our highway…

Are you missing a rooster?

Hello Kate,

A rooster has been seen on the Bobcat Trail in Andrew Molera State Park adjacent to Hwy 1 several times over the last couple of weeks. He was last seen today but has eluded capture.

72A9E459-6B83-42F8-8F6A-49F672A47AA2

Specifically, we’ve had reports of the rooster on the Bobcat Trail anywhere north of Cpt. Cooper School all the way to the main park entrance. If somebody happens to be missing a rooster in the area, that would be the place to start looking.

Many thanks,

Matthew Khalar
