(CNN) About 1,250 lightning strikes were recorded in western Washington state during a storm that caused widespread power outages Saturday night, the National Weather Service said.
A strong line of thunderstorms developed over western Washington, bringing frequent lightning, heavy rains, flooding and hail to the Puget Sound region, according to the National Weather Service's office in Seattle.
The 1,250 lightning strikes were between 6 p.m. and 9 p.m. local time, it said. Of those, 200 were recorded in the Seattle metro area from 8 p.m. to 9 p.m.

In our June 3 article there was a discussion of personal lightning safety and preparedness for both the outdoor and indoor risk. In our June 10 article the discussion centered on the more frequent but less severe INDIRECT lightning strikes that can result in a surge capable of damaging your appliances and electronics. This article will address the less frequent but potentially more severe DIRECT lightning strike to your home.
What is the chance that my home will experience a direct lightning strike?
A direct lightning strike does not happen very often, but it can cause substantial structural damage with ensuing fire. The chance that your home will be struck is very very low, but it is not zero and is greater than winning the lottery.
This was demonstrated on Sunday, June 9 when The Villages Public Safety Department responded to several calls during a severe thunderstorm with cloud-to-ground lightning strikes. The garage of a home in Poinciana was struck and the ensuing fire heavily damaged the garage and the attic but thanks to the prompt action of firefighters it was contained to the area of origin.
This is the 18th home since 2004 that has either been destroyed or in this case damaged to the extent that it is not habitable. In none of these cases did the home have a lightning protection system (LPS) commonly called lightning rods.
Recognize that in our area we typically experience more than 100 thunderstorm days each year and all thunderstorms have potentially dangerous lightning. Another metric is that each square mile will receive about 40 cloud-to-ground strikes annually, according to Dr. Martin Uman’s book, The Art and Science of Lightning Protection.
What can be done to mitigate a direct lightning strike to your home?
Consider providing a LPS like ones that have been protecting people and property worldwide for more than 260 years. They have been the subject of numerous studies over the decades including rocket-to-wire triggered lightning research at the University of Florida.
You may have noted that The Villages has installed LPS on every pumping station, all sewage treatment plants, fire department headquarters including the adjacent emergency operations center, and nearly every building at Sumter Landing. Hospitals and educational facilities are required to be protected by the building code. Most large churches and hotels in the area also are protected, as is the Sharon Performing Arts Center and the Savannah Center, among many others.

McHenry County and the Village of Barrington Hills should be held responsible for damages and emotional suffering caused by a lighting bolt that hit a house in the village last month, according to a $3 million lawsuit filed in McHenry County.
The suit, filed by Robert and Alicia Olson, claims their 5-year-old son was almost killed by the lightning strike April 22 at a home the family has been leasing for three years on Haegers Bend Road. It claims that local and county officials should have known that lightning is a threat to homes in the area, and should have required lightning rods or other lightning-capturing systems to be installed.

Through August, September and beyond, meteorologists keep their eyes fixed on computers tracking weather patterns from the west coast of Africa which might become tropical storms or hurricanes as they cross the Atlantic ocean. Summer is usually a rainy season in Central Florida, with frequent thunderstorms, making us the ‘Lightning Capital of the U.S.’ Whereas The Villages area, with an average of 80 thunderstorms each season, ranks lower than Tampa Bay, which has recorded an average annual thunderstorm count of about 100, we have had our share of storm-related tragedies.
Historically, lightning has been a problem in many places on planet earth. In 1776, the famous bell tower in Venice’s St. Mark’s square was destroyed by lightning; and gunpowder stored nearby killed 3,000 people in the ensuing fire and explosion. Subsequently rebuilt towers there have burned down nine times. Today that campanile has good lightning protection!
Local Villages lightning gurus, Len Hathaway, and electrical engineer, Bob Freeman, are firm believers in lightning protection systems. “It’s ALMOST always a beautiful day in The Villages,” Freeman and Hathaway like to quip. They have amassed much knowledge from their long careers involved in lightning, and offer orientation
Some residents may be evaluating their need for a lightning protection system (lightning rods) as we seem to be in the midst of a very active lightning season. The National Weather Service’s historic data shows that on average we get 80 thunderstorm days a year. By the unofficial count of one local weather observer we are now up to 65 days and we still have all of August and the balance of the year to go.
With the direct strike resulting in the destruction of a home in Pinellas in June and last year in Calumet Grove plus the heavy damage to a home in Belvedere on July 11, 2014, some residents may be considering lightning rods. Lightning rods have been silently diverting potentially destructive lightning strikes harmlessly to ground since Benjamin Franklin’s discovery 262 years ago.
Should you consider installing lightning rods? Only you can answer that question. Do you have a high or low tolerance for risk? For example, if you have a high tolerance for risk you do nothing, the odds are with you (nine homes destroyed in last 10 years), the money stays in your pocket and if the worst does happen you have transferred the monetary risk via insurance.

A Spartanburg Way home in the Village of Virginia Trace burned down last month when lightning struck the unoccupied house and went unnoticed for over an hour. The delay in alerting and reporting was due to the lightning strike causing a fire to start in the attic, where there was no fire/smoke detector. The Villages Public Safety Department quick response when called resulted in no collateral damage to neighbors’ homes.
A second home was destroyed on Pelican Path less than one week later by a massive lightning strike, which didn’t give quick responding neighbors and firefighters a chance to save it. Fortunately, no one was injured and no collateral damage was suffered by adjacent homes.
The Villages is within the Florida region sometimes referred to as the lightning capital of the world. Therefore, we have to be vigilant and respectful of the potential safety hazards associated with our storms. We should consider detecting devices in garages and attics, as well as, the living areas. We should also be aware that golf carts don’t provide the same security in a lightning storm as an automobile. Please also be aware that we are responsible for our own safety on the ball field and golf course.
The best advice the VHA can give our residents is to seek shelter in a lightning storm and have alerting systems in your home. NOAA weather alert radios give emergency warnings within the county. Weatherbug (#) provides real-time tracking within The Villages to The Public Safety Department and emergency information, including lightning strikes within six miles, to cellular phones for subscribers. CodeRED can also give emergency weather alerts to your home phone.
Free home security inspections may be scheduled with the County Sheriff’s office (Sumter County 753-2799). Many home inspection/fire safety checklists are available online, and one provided in this issue of The Voice for review. Fire Inspector Dan Hickey is available for questions concerning fire safety at The Villages Public Safety Department (205-8280). Public Safety Department personnel at any fire station in The Villages will also assist you in properly programming your NOAA weather alert radios.

To the Editor:
I would assume that homes struck by lightning that have the greatest threat for serious damage or total destruction are those with natural gas. The lines run in the ceiling area and are most likely to be ruptured during a strike. A fire would be out of control very quickly.
A calibrated excess gas flow valve can be installed outside the home for a fraction of the costs of lightning rods. I sleep better at night during storms knowing it is in place.
