Studies Show ...................

Winter Storms Cause More 
Wild Power, phone line outages, surges, spikes and interference
than Summer Storms

On the other hand, There are more Summer Storms

Winter Storm Spherics cause up to 50% as much damage as Summer Lightning Storms

On the other hand, WHY SUFFER ANY STORM DAMAGE ?
