With Memorial Day marking the unofficial start of summer, the National Weather Service is reminding us about the dangers of summer weather.

Ed Shimon with the National Weather Service in Lincoln indicates they have been running a social media campaign on heat safety. 

Shimon says humidity makes the heat more dangerous as it is harder for the body to produce perspiration and cool itself. He suggests keeping the heat index in mind when outdoors on a hot day.
