Here's the latest update on road conditions from Sheriff's Lt. Sean Gerrity:
Since about 6:30 AM, there have been showers in the area of varying intensity, at times heavy. Except for the apparent re-flooding at Pauma Reservation Road and Highway 76, which apparently caused a collision this morning, I have not had any additional debris flow activity reported since last night. At least four watersheds in the burn area visibly had debris flow crossing and/or traveling down local roadways.
Adams Road/Pauma Reservation Road: There is a burn area watershed, rated as having an 80-100% probability (2 year and 10 year return interval) of releasing between 1,000 and 10,000 cubic meters of debris clearly did so (easily between this estimate range). The unnamed creek at the base of this watershed apparently feeds through a culvert, which appears to be buried, now. It nearly aligns perfectly with the straight portion of Adams Road that leads directly to Pauma Reservation Road. This creek intersects with Adams road on Thomas Brothers Map Page 1031 A7 (also, approximate coordinates of 33° 20‚ 18.02N, 116° 59‚ 10.12W). The deep debris and mudflow went over Adam Road (or possibly broke through Adams road, but I could not tell), down the creek, and also easterly around the small curve on Adams Road, then straight down Adams Road onto Pauma Reservation Road. It continued down Pauma Reservation Road onto Highway 76. Pauma Reservation Road/Hwy 76 was cleared and opened last night, but apparently had more flow back onto Highway 76 later this morning, apparently causing a non-injury collision after sunrise this morning. The portion of Adams Road from the creek's intersection to Pauma Reservation Road is so deep with debris and mud that it was not passable when I viewed it earlier, not even with my 4WD. There are at least four citrus agriculture residents long this portion of the roadway. If they did not pre-evacuate, they are likely unable to leave until County Roads can clear the debris. I could not enter the area to check these residences. The creek itself also had debris flow over Adams Road, which crossed Citricado Road, also. I believe this is the same watershed that released debris onto Adams Road during the weekend of November 30, 2007. County Roads has been notified, and CalTrans was working to clear the debris and water flow that flowed across and westbound along Highway 76 from Pauma Reservation Road, at the site of the collision.
There are two smaller watersheds adjacent to and directly west of this watershed, that also have flow paths that cross Adams Road. These are both in the burn area but are unrated on the debris flow maps. Both of these also had mudslide activity crossing Adams Road, with the one furthest west causing about 12" of steep mud across Adams Road, only passable with a four-wheel drive vehicle. I found an abandoned car stuck in this flow location.
Highway 76 west of South Grade: This is precisely the same location of the mudslide that occurred during the weekend of January 4, 2008, with at least the same amount of debris flow. This flow apparently (again) came from the watershed west of South Grade Road, estimated for a 1,000 to 10,000 cubic meter flow potential (61-80% probability in a 10 year return interval). CalTrans is currently directing traffic on one lane around the deeper water flow on the westbound side, while trying to clear the clogged culverts.
South Grade Road (S-6) at the 45 mile marker (above the 4,000 foot elevation level): This location is now cleared, opened around 9:30 AM. This was actually more of a rock slide, with rock that broke through a metal retainer intended to protect the roadway from such a slide at this particular curve. The metal mesh-type retainer is still intact and full of rock, but apparently much of the rock broke loose and subverted it onto the roadway. The mesh is on the west side of the road, at a location where the roadway was clearly cut into the mountain beneath this rock, which rises almost vertically and fairly high above the roadway at this location. Although this is in the burn area, it is not clear if this rock slide occurred as a result of the burn, or would have occurred anyway.

HWY 76 REOPENED
Highway 76 has been reopened after being closed most of the night. Cal Trans workers are directing traffic around the mudslide location for now. Hopefully it doesn't rain too much to cause another river...
ROAD CLOSED AT THREE POINTS
Here's the latest from Lt. Sean Gerrity on road closures due to rain:
We've have mud and earth/debris slides reported at three locations, all occurring between about 9:00 PM and 9:30 PM earlier.
- South Grade Road at about the 45 mile marker (apparent earth slide and/or debris slide), about 3/4 the way up Palomar Mountain from Highway 76. South Grade Road is completely impassible, and has been closed. County Roads is handling the closure (at this time, presumably between Highway 76 and East Grade Road [S-7]). La Jolla Fire Chief Wes Ruiz reported it may take a day or more to clear this. Supervisor Burt Quick from DPW/County Roads is evaluating this. Although he had not arrived to personally evaluate the site, from what he understands it might be possible to open one lane of travel rather soon, and perhaps even the entire roadway within five or so hours.
- Highway 76 just west of South Grade Road (mudslide/debris flow). Highway 76 is closed between Valley Center Road and the Lake Henshaw resort (residents and business employees of Palomar Mountain can access the mountain via Lake Henshaw and East Grade Road only). CalTrans initially requested closure, and I sent SDSO units to do so until they could be relieved by CHP. CalTrans cleared the mud debris off of the road itself, and thought it would be okay, until the next heavy rain burst happened on Palomar Mountain above. There are two culverts clogged, and the rain burst above caused a fairly sizeable river to flow over the road down below rather than through the culverts (water deep enough to cause spin-outs and/or drown cars). Sporadic shower activity, forming roughly off of the Oceanside coast and passing this way, continued to develop until about 2:00 AM. Local weather is currently calm, with significantly reduced shower activity forming off of the Oceanside coast. Per a conversation Rand Allan had with NWS at about 11:00 PM, further potentially heavy showers are anticipated from a system currently north of us, off of the Los Angeles coast, expected to arrive between 3:00 AM and 6:00 AM (if conditions don't change). CalTrans has to bring in heavy equipment in the morning to clean out the culverts, before they can open the road again. This happened a few weeks ago at the same spot, and they had it opened by about 1:00 PM. Hopefully the damage is the same or less than the last time.
- Pauma Reservation Road north of Highway 76 (mud debris). CalTrans and/or County Roads have cleared this of mud debris and it has been re-opened.

SOUTH GRADE CLOSED BY ROCK SLIDE
MUDSLIDES
The debris flows that have been feared since the October fires occured Sunday night, closing S-6, the South Grade Road to Palomar Mountain.
The heavy rains that had been anticipated all weekend began pelting areas that had been burned, and which were prime candidates for mud and rock slides, called debris flows.
Your Roadrunner reporter personally came upon the rockslide about three quarters of the way up the grade at about 10 p.m. Sunday night as I was returning home
Most of the road up the grade was overrun with gravel and large rocks. Fog and rain were alternately thick and heavy as well, so that it was hard to tell where the road left off and the debris began.
So much so that I considered very strongly turning around and going back down even before I encountered the Dept. of Public Works bulldozer that was working in the fog, moving piles of rocks out of the way.
The bulldozer’s operator got out of the rig and approached.
“You can’t go any further. It’s impassable. There’s hundreds of tons of rock on the road,” he said.
I made a U-turn, and so did a car that had been following me up the grade, and who turned out to be an astronomer of who was heading to work at “The Monestery,” at Palomar Observatory.
It could be a day or perhaps much longer before the road is reopened, especially if the debris flow has damaged the road structure.

FLASH FLOOD WARNING
A while ago I asked Sheriff's Lt. Sean Gerrity for an update on the possible flooding situation. He just replied:
"For a while today, we had a nice break. Right now, there is a string of thunderstorm cells coming in, and a flash flood warning (elevated from a "watch") was issued for our area just after 4:00 PM. It looks like there may be a little rest between some of these cells for a short period, but the weather seems to have more in store for us tonight. I was able to close my command post earlier today, but I am now coming in to open it back up.
Thus far, there has been no visible debris flow activity and thus no related road closures or higher reverse 911 alerts. We are all hoping it stays that way.
Stay dry,
Lt. Gerrity
