The Benefits of Having an Expert on Your Side

Lightning Strikes
Lighting Conditions

Plaintiff slipped and fell on snow/ice in a parking lot during the afternoon of March 2, 2018. At the time of the slip & fall, a storm was ongoing with heavy snow and gusty winds. The National Weather Service had a Winter Weather Advisory and High Wind Warning in effect. Summary judgment was granted in favor of the defense.

Plaintiff was pouring concrete on a roof when they were fatally struck by lightning. A Special Weather Statement was issued by the National Weather Service indicating a storm was in the area and could produce frequent dangerous cloud to ground lightning strikes, with additional forecasts for thunderstorms up to 72 hours in advance. Lightning was visible in the distance as the storm approached the area according to witness testimony.

Plaintiff was crossing the street on a bicycle when an oncoming car struck them. Defendant claimed they could not see the plaintiff due to the sun hitting the trees and casting shadows on the road. The altitude and azimuth angles of the sun had to be calculated to show that the sun would not have produced any glare that would have impaired the driver's vision.
