BUSINESS OPERATION CENTER SITUATION REPORT 7/29 /18 1900H STATEWIDE WEATHER SYNOPSIS NORTHERN CALIFORNIA Weather of Concern • Heat continues to linger over northwest California mainly with the valleys of Trinity and Mendocino counties, having the hottest locations. • Hot weather will continue today over the entire San Joaquin Valley, Sierra Foothills (including the Ferguson Wildfire Operation Area), and the Kern County Desert. Strong high pressure will continue producing hot and dry conditions throughout Northern California through Tuesday, except along the immediate coast where the marine layer will keep conditions cool and humid. Winds aloft are light out of the SW, but at the surface local winds associated with the thermal low and the sea breeze are making it difficult to control ongoing wildfires. Thick smoke from the ongoing wildfires is trapped under the high pressure in many areas, and this holds temperatures down and weakens the effect of the inland thermal low. Each day through Tuesday, from the late afternoon hours until late evening, SW to NW winds will gust to 15-25 mph through the gaps and passes in the coastal mountains into the west side of the Sacramento Valley. Inland overnight RH recovery will be only to 25-40%. These winds gradually weaken from midnight until sunrise, then start up again in 2 the afternoon. Inland temperatures will peak at 4-7 degrees above normal with minimum RH 5-15% in the driest areas. Areas with thick smoke will see temperatures closer to seasonal averages. On Monday and Tuesday, the high will shift a bit east and the SW flow aloft will become a bit stronger. It is unlikely that winds will be strong enough to disperse the smoke much, however. The marine layer will move a bit farther inland Monday and Tuesday. Isolated showers and thunderstorms may move up the Sierra from the south into our eastern areas Tuesday afternoon. Wednesday the high will weaken as a low pressure trough in the Pacific NW pushes south. A stronger westerly flow can be expected along with higher humidity, cooler temperatures and higher overnight RH recovery that will last into next weekend. SOUTHERN CALIFORNIA Weather of Concern • Prolonged periods of dangerously hot temperatures will occur. The combination of hot temperatures and high humidity combine to create a dangerous situation in which heat illnesses are likely • Hot and dry with poor overnight relative humidity (RH) recovery inland from the coast through Tuesday • SW-NW gusts 15-25 mph through coast range gaps and passes into Western Sacramento Valley from late afternoon until late evening daily through Tuesday Increasing wet thunderstorms across Southern California. Well above normal temperatures across inland areas this week. Lower afternoon RH over Central CA through Friday. The persistent high pressure ridge over the Southwest will edge a bit further eastward the next couple of days. This will allow easterly flow to develop, which will transport some monsoonal moisture into the Southern half of the district during the first half of the week. The deepest moisture is expected to remain south of the border, but this afternoon, isolated wet thunderstorms will be possible in the San Bernardino and Cleveland National Forests. One or two storms may occur along the Sierra Crest as well. Despite the increase in moisture, thunderstorm coverage is expected to be isolated due to a thick band of high clouds moving in from the east. Monday and Tuesday, storm coverage is expected to be greater and easterly steering winds may allow for some storms to reach the foothills and Inland Empire. This moisture will gradually retreat southward, resulting in fewer storms by Wednesday or Thursday. Temperatures will remain 5-10 degrees above normal throughout the week with highs in the upper 90s to 104 in the valleys and up to 118 in the low desert. Relative humidity will be high over Southern California, but some interior valleys of the central coast and Sierra Foothills may see readings in the 8- 15% range for a few hours each afternoon this week. Winds are expected to be light, except near thunderstorms. 3 INLAND REGION FIRES Ferguson, Vegetation Fire, Mariposa County Location: Hwy. 140 x Hite Cove, Near El Portal Jurisdiction: Federal DPA, FRA, Madera-Mariposa-Merced Unit/Sierra National Forest Start Date/Time: 07/13/18 at 2035 hours Per Cal OES Duty Officers and ICS-209 as of 07/29/18 at 0805 hours: • 53,646 acres, brush and timber, 30% contained • Expected Containment: 08/18/18 • Threatened Structures: 5,171 single residences, 3 multiple residences, 7 mixed commercial/residential, 20 non-residential commercial properties, and 35 other minor structures. • Destroyed Structures: 1 other minor structure • Unified Command with USFS, CAL FIRE and Mariposa County Sheriff • Park Service and Forest Service are in joint delegation\Moderate fire behavior with backing, flanking and group torching • Fire is burning in a high tree mortality area • 1 Firefighter fatality Proclamations • On 07/15/18, Mariposa County submitted a Proclamation of Local Emergency.
