TODAY’S INFRARED MAPS KEY:

IMPORTANT NOTE – NO IR FLIGHT YESTERDAY WHITE PERIMETER IS FROM 2045PDT 10/4/2021 AND SHOWS ROUGHLY 48 HOUR GROWTH TO RED PERIMETER. Giant Sequoia Groves are SHADED GREEN. Past 10 years of (Rx) prescribed fire is SHADED DARK BLUE👇


Overview looking northeast over the KNP Complex.


-Maps start at Mineral King road and progress clockwise around the fire-

As of 11pm last night, fire has NOT spotted over the East Fork Kaweah River.


Looking north where a spot fire crossed the north fork of the Kaweah River on September 30. KNP made a big run to the north over the last week. The isolated white perimeter along the General’s Highway in the northern portion of the map is from firing operations on October 4 into the Redwood Mountain Grove.


Same area showing SEQUOIA
GROVES and Prescribed fire Rx within the last 10 years.


Looking west from the Dorst campground. Fire spread through portions of the campground over the past few days. The fire also burned through the Lost Grove and crossed the General’s highway, spreading north towards Stony Creek.


A familiar view from the road inside the Lost Grove.


Looking west above the Middle Fork Kaweah River. Firing ops securing the Giant Grove near Tunnel Log.


A familiar view of Tunnel Log.


And finally, looking west from Empire Mountain. Fire continued to move within the Castle Creek drainage. And fire also continued to move through the Atwell Grove near Camp Conifer.

 

*** 8:45pm on October 5 – INCIWEB update.

Significant Events Observed Fire Behavior:

Active, Uphill Runs, Running,

Short-range Spotting

Narrative:

A decrease in fire behavior from the increase in humidity. Some active to very active fire behavior with upslope runs.

 

Outlook

Planned Actions Utilize direct and indirect tactics including firing operations, ground resources and heavy equipment.

Structure protection and perimeter control measures will be taken around structures within threatened communities.

Conduct structure protection and mitigation efforts for National Park features (infrastructure, Headquarters, Museum, employee housing) and adjacent communities.

Continued protection and mitigation measures for all sequoia groves within the fire area. When attributes of fire behavior are favorable to the landscape, allow fire to spread to aid in fuels reduction in around the groves.

 

Projected Incident Activity 12 hours: Fire behavior will moderate through the night as the humidity increases. Downslope winds will continue to influence fire movement.

24 hours: Fuel moisture increase with the higher humidity. Expect fire behavior to be moderate to active unless fuels, slope and winds align then very active fire behavior is possible.

48 hours: Cloud cover along with higher humidity will lower fire behavior with moderate being the most common.

72 hours: Precipitation will keep the fire behavior low and limit growth.

Anticipated after 72 hours: Moist fuels will keep fire behavior low.

 

Current Weather

Weather Concerns Low pressure to the south brought slightly increased humidity, along with southerly flow aloft. This continued to push smoke northward through the day. Winds aloft will continue from the south and west during the next few days as another trough moves down the California Coast.
