Wind Dynamics

first 2 will be pulled from the fire automatically.

Can have dynamic values. Ie > Higher wind value raises directional randomness value.

Wind Speed

Controls the velocity of particle movement, simulating how wind speed affects ember and heat plume transport.

11mph

Wind Direction

The prevailing direction of the wind as provided by the closest NWS weather station, expressed in degrees.

N(0)E(90)S(180)W(270) 0degrees

Directional Randomness

Simulates turbulence and local wind variations by adding random fluctuations to particle trajectories, similar to fire-induced wind eddies.

12%
Particle Dynamics

Can also have dynamic values. Ie > Higher wind reduces scale decay. Or Higher acreage increases. More than 30 hotspots increases particle lifespan. Etc.

Particle Lifespan

Determines how long each heat visualization element persists, analogous to the duration of visible thermal signatures in infrared imagery.

30frames

Particle Density

Controls the concentration of visualization elements within each burst, similar to the density of detected thermal signatures in a given area.

20%

Particle Scale Decay

Determines how quickly particles diminish in size over their lifespan, representing the cooling and dissipation of thermal signatures.

60%

Particle Scale Variation

Controls the range of initial particle sizes, simulating the variation in intensity of thermal signatures across a detection area.

80%
Burst/Emitter Dynamics

(⛔️ Some of these aren't totally working.). Controls the detailed behavior of fire particle emission patterns.

Burst Frequency

Sets how often new groups of particles are emitted, simulating the pulsing nature of thermal plumes and intermittent fire behavior.

2per sec

Particles Per Burst

Determines the number of thermal signatures released in each emission event, representing the intensity of individual heat releases.

3

Burst Duration

Controls how long each emission event lasts, analogous to the duration of individual thermal pulses in fire behavior.

0.3sec

Gap Between Bursts

Sets the cooling or rest period between emission events, representing the cyclical nature of fire intensity fluctuations.

0.2sec

Burst Length Variation

Adds randomness to the duration of each burst, simulating the natural variability in fire behavior and thermal signature patterns.

1. Start Time & Info

**Start Date/Time/Location** The Border 2 Fire started on January 23, 2025, at 2:31 PM, near Otay Mountain Truck Trail within the Otay Mountain Wilderness in San Diego County, California[5]. **Size and Containment** As of the latest updates, the fire has burned 6,625 acres and remains 10% contained[1][5]. **Growth and Rate of Spread** Initially reported as a smaller fire, it has grown significantly due to the dry and windy conditions in the area. However, recent rain has significantly helped in slowing down the fire's spread[1]. **Containment Efforts** Firefighters from CAL FIRE San Diego Unit, along with other resources, are actively working to contain the fire. The rain has aided in turning the red line to black on the fire map, indicating controlled areas[1].

2. Evacuations & Closures

**Evacuation Orders and Warnings** As of the latest updates, all evacuation warning areas have been lifted in the City of Chula Vista. There are currently no evacuation orders or warnings in effect[2][5]. **Evacuation Shelters and Information** Residents are advised to stay informed through the Genasys Protect App and Alert San Diego for any potential evacuation information[2]. **Road Closures** Some road closures have been lifted, including both directions of travel on state Route 94 and Alta Road near Otay Mesa Road. However, Otay Lakes Road at Wueste Road remains closed to all vehicle traffic[1][2]. **For more information, visit:** - [CAL FIRE's Border 2 Fire page]: https://www.fire.ca.gov/incidents/2025/1/23/border-2-fire - [City of Chula Vista's Border 2 Fire updates]: https://www.chulavistaca.gov/Home/Components/News/News/3880/3175 - [San Diego Sheriff's Department updates]: https://www.sdsheriff.net/newsroom/releases.html

3. Current Impact

**Injuries and Fatalities** There are no reported fatalities or injuries directly attributed to the Border 2 Fire[1][2][5]. **Structures Impacted** The fire poses a threat to critical communication infrastructure on Otay Mountain Repeater Site, but there are no reports of structures destroyed or significantly damaged[5]. **Power Outages** There are no specific reports of power outages directly related to the Border 2 Fire. **Notable Impacts** The fire has been visible to the Chula Vista community, and while it is no longer an imminent threat to life and property, it remains active and visible[2].

4. Current Outlook

**Containment Projections** Despite the fire being only 10% contained, the recent rain has significantly aided in the firefighting efforts. However, there is still a lot of work to be done, especially in the wilderness areas[1]. **Weather and Wind Warnings** The rain has helped mitigate the fire's spread, but ongoing monitoring is necessary due to the potential for changing weather conditions. There are no current red flag or high wind warnings in effect, but the situation is being closely monitored[1][2].

5. Weather info

**Cause** The cause of the Border 2 Fire is currently under investigation[5]. **Weather and Climate** The fire was initially fueled by dry and windy conditions typical of the region. However, recent precipitation has significantly helped in controlling the fire. The ongoing weather conditions, including the rain, have played a crucial role in slowing down the fire's spread and aiding containment efforts[1][5].
