DRY LIGHTNING RED FLAG WARNINGS - NORTHERN CALIFORNIA
LIGHTNING STRIKES IN NORTHERN CALIFORNIA BETWEEN SEPTEMBER 9-12, 2011, are predicted at this time.
CALFIRE MOVING CREWS INTO SOME AREAS IN NORTHERN CALIFORNIA AS THE DRY LIGHTNING STRIKES COULD BE SIMILAR TO THE LIGHTNING STRIKES IN 2008, ACCORDING TO CHANNEL 7 NEWS 6:15 A.M. on September 8, 2011...SEE NEWS CLIP BELOW.
PLEASE KEEP DETAILED RECORDS OF SKIES IN THE NEXT FEW DAYS-RECORD & PHOTOGRAPH SKIES & ANY UNUSUAL EVENTS IN YOUR AREA...THIS LIGHTNING EVENT COULD BE A LIGHTNING EXPERIMENT. The lightning strikes in June 2008, were the worst in recorded California history with thousands of dry lightning strikes, in some area, per hour, which caused major forest fires in Northern California.
Please stay alert during the next few days for any signs of lightning or smoke from forest fires in your area-especially in Northern California.

USA Today - "Shocking: World Record 199-Mile-Long Lightning Bolt Reported"
September 16, 2016
"...Scientists identified all-time world records for both the longest lightning bolt and the world's longest-duration lightning flash..."
Longest Lightning Bolt Happened in Oklahoma in 2007. The longest duration flash, 7.4 Seconds, Happened in August 30, 2012 in France.
CalFire Preparing for Lightning Strikes

"...The California Department of Forestry and Fire Protection is increasing staffing due to predicted dry lightning and strong winds throughout Northeastern California.
Midweek, an upper level low was expected to approach the California Coast, drawing in monsoonal moisture, which is predicted to trigger dry lightning across the Northeastern section of California including Lassen, Modoc, Siskiyou and Shasta counties. In response to the predicted dry lightning, Cal Fire is moving fire engines and resources into the areas expected to see an increased fire danger.
As this low moved into Nevada on Thursday, it was expected to shift winds to the northeast, creating breezy and dry conditions into Friday across most parts of Northern California, including the areas where the dry lightning is predicted to hit.
In addition to the prepositioning of fire engines, Cal Fire is also staffing all reserve fire engines, staffing additional inmate fire crews 24 hours a day, and plans to hold all personnel on duty.
"The forecasts indicate weather conditions could be similar to the lightning siege we experienced in 2008 when the state saw nearly 2,000 lightning sparked fires," said Chief Ken Pimlott, director of Cal Fire. "Cal Fire's firefighters are ready to respond if more fires do break out, but we especially need the public to be extremely cautious, because we don't need any additional fires."
Cal Fire urges Californians to remain extra fire safe and help prevent new fires:
Any mowing or weed eating should be done before 10 a.m. (and NEVER during extremely dry conditions). Never use lawn mowers in dry vegetation. Ensure campfires are permitted and, if so, be sure to extinguish them completely when done. Never pull over your vehicle in tall dry grass..." End

Atmospheric Scientists Link Lightning to Ice Particles In Clouds
October 1, 2006 — Satellite imaging is now helping atmospheric scientists link the amount of charged ice in clouds to lightning activity. Ice particles in thunderstorms can help increase precipitation, the scientists found. Different-sized ice particles within a cloud also carry a positive or negative charge, and as the particles collide, that charge builds up, leading to lightning. See the Video on Lightning in this video. (With this knowledge it would appear that Lightning can now be manipulated by atmospheric experiments.)
