Smoke Impact Forecast #4
Soberanes Wildfire
Air Basin: North Center Coast CAL
Fire IMT 4 w/ USFS
Issued for August 1st, 2016 Prepared by: Gary M. Curcio
Time: 11:18 AM Air Resource Advisor
Smoke Synopsis:
|
Yesterday: The acres contributing to the fire emissions
increased 2,707 acres. At the day’s
end Carmel River School was the most severely impacted station as was the
Carmel Valley. The geographic position of the Valley in relation to the fire
and natural diurnal surface wind flow will sustain this impact. The Salinas
Valley communities tend pick up their poorest AQ from 11AM to 2PM. All
stations did experience degraded air quality with the exception of Santa Cruz.
Today: Smoke impact is anticipated to be
significantly higher. The suppression effort is planning to conduct a burnout
operation. This operation is planned for each day thru Thursday. This increased smoke production has been
factored into the AQ Table. Carmel River School & the Carmel Valley are
expected to be the most impacted areas. The heaviest smoke will reside in the
Coastal Range and above the marine layer. The upper level drift smoke will continue
impacting San Joaquin Valley and Sierra foothills. Lower layered smoke will be
in the Carmel & Salinas Valleys. It is expected to affect northern
communities and communities to the East and SE of the fire for the next
several days. The influence of the South/Southwest
airflow remains.
Tomorrow: Expect elevated smoke levels. Degraded
AQ is to last through the week.
