Thus, have decided to High Risk the mountain and Far Eastside as a result. As is the case with these types of Monsoon Surge events, coverage patterns and storm wetness will get fine tuned as we get nearer to the event but there is enough evidence to support the High Risk. The initial Monsoon Surge will begin late tonight with isolated thunderstorms possible across the far south including the Tahoe Basin and Bay Area. The threat for isolated thunderstorms will remain Friday and Friday night as the moisture flow moves northward, especially favoring the coastal range within the Mid Coast-Mendocino as well as the Northern Sierra and Far Eastside . The initial activity looks to be drier for most of the area except for perhaps the Tahoe Basin. Monsoon moisture will settle over the area during the weekend with the High Pressure back over the Four Corners and a deepening low off the coast. Storm coverage should increase then although storm wetness will also increase with a mixture of wet-dry or smaller footprints of wetting rain. Larger footprints of wetting rain could potentially be found across eastern portions of the area but decided to throw those in the High Risk due to the amount of potential lightning. Residual lightning impacts (isolated) should remain Monday into Monday night before a drying pattern begins. Hot temperatures will remain the next 7 days although the added cloud cover and Monsoon Moisture push will take the edge of the afternoon heat. Strongest gusts near term will be found across the NW corner (gust to 20-25 mph) as well as throughout the greater Bay Area during the late afternoon's and overnight's. Gusty wind and low RH will align across portions of Del Norte and Siskiyou counties the next 48 to 72 but the areal coverage is small so decided not to High Risk it. Humidity values will gradually trend up. SOUTHERN CALIFORNIA ***Scattered wet thunderstorms today, mainly over the Sierras*** ***Drier and hotter next week*** Monsoonal flow is ebbing this morning and this will result in fewer showers and thunderstorms over the next two days. But strong sunshine may allow convection to initiate a couple hours earlier over the mountains with a few places seeing convection begin by noon. Most of the storms will occur on desert-facing slopes of the Angeles, San Bernardino and Cleveland National Forest as well as the Sierras. Brief heavy rain will be possible from the storms as they move northwest at 10-15 mph. Temperatures today will be a couple degrees warmer over Southern California due to the lack of clouds, but the central part of the state will see a modest cooling trend through Friday due to a trough over the Pacific Northwest. Highs will range from the upper 90s in the interior valleys and the San Joaquin Valley to 108 in the low desert. Minimum RH will be above 25% except across the central coast interior where some locations will see readings in the teens today and Friday. This weekend, high pressure will begin to build directly overhead, leading to warmer, less humid weather. Temperatures will be close to 100 degrees across interior valleys of Southern California, 103-105 in the San Joaquin Valley to 115 in the low desert. Isolated afternoon thunderstorms will still be possible near the Sierra Crest, but they will be short-lived and anchored to the highest terrain. Expect further warming next week as this ridge strengthens. By Tuesday and Wednesday, highs will be up to 108-110 in the valleys with daytime RH falling close to the single digits each afternoon. It will remain very warm through the end of the month, but winds should remain light throughout the extended period. -- 3 -- Red Flag Warnings & Watches Current Red Flag Warnings & Watches Source: https://www.weather.gov/fire/ (July 20, 2018 12:01am) Current Watches, Warnings or Advisories for California Link https://alerts.weather.gov/cap/ca.php?x=1 -- 4 -- Significant Fire Potential Maps Friday Saturday Sunday Monday Tuesday Wednesday Source: http://psgeodata.fs.fed.us/staticmap.html -- 5 -- California Current Air Quality Map Source: https://www.airnow.gov/index.cfm?action=airnow.local_state&stateid=5&mapcenter=0&tabs=0 Legend: AQI = Air Quality Index; PM = Particulate Matter; O3 = Ozone Air Quality Index Basics Overview: https://airnow.gov/index.cfm?action=aqibasics.aqi -- 6 -- Stoney Fire - Butte County — Newly Added Fire — Acres Burned % Contained [Change] [Change] 962 (1) 98% (1) Start Date Estimated Containment Date July 12, 2018 (1) July 20, 2018 (3) Lead Agency(ies) Chico City Fire (1) Location Bidwell Park, Upper Park Rd, Chico (1); Six miles northeast of Chico (2) Structures Structures Fire Maps Threatened Destroyed None (3) None (2,3) Evacuations None listed (1,2) Other Infrastructure Threats None listed (1,2) Projected Fire Activity Minimal fire behavior.

Nearby Zip Codes: 93526 Firefighters cannot access this flank of the fire. As such, firefighters are using a confinement strategy in this area. There may be continued fire activity as fuels dry out and fire activity picks up. The fire will eventually “rock out” as the fire reaches the granite cliffs and the absence of fuel.
