A man struck by lightning while swimming Saturday night at Beltzville State Park died early Sunday morning.

Jose Lopez-Hernandez, 38, of Camden, NJ, was pronounced dead just after 3 a.m. at Lehigh Valley Hospital-Cedar Crest.The incident took place just after 7:30 p.m. on Saturday and, according to scanner reports, crews on scene were attempting CPR before transporting Lopez-Hernandez to the hospital.An autopsy is scheduled for Monday.The Lehigh County Coroner’s Office and the Pennsylvania Department of Conservation and Natural Resources are conducting an investigation."It’s a very unfortunate situation," said Devin Buzard, Beltzville State Park manager. "It’s so imperative that people take the proper precautions when a storm is coming."Buzard said Beltzville has a protocol during a storm and it was followed Saturday.At the first signs of lightning, the staff will make an announcement over the public communications system, telling people they should leave the water.When or how quickly that happens, however, is up to the individual."We can do all we can, but we can’t physically force someone out," Buzard said. "There was an announcement made to seek shelter. It was a humid, muggy day and the storm rolled up quickly."While most of the lightning activity was "cloud-to-cloud," according to the National Weather Service, there were more than a few reportable ground strikes on Saturday.In the 30 minutes surrounding the incident at Beltzville, the area saw about 10 to 20 other strikes, or three to four every five minutes."That’s significant activity," said Valerie Meola, NWS meteorologist, "but there are some violent storms with 100 strikes every five minutes. There can be a lightning strike 5-10 miles from the eye of the storm so while it may seem far away, when there is any thunder you can be struck by lightning."The amount of staff members making announcements varies based on how many are working at the time. Buzard said around 7:30 p.m., only one or two people are on duty, as opposed to four or five during peak hours.Around 3,000 people were at Beltzville on Saturday during the afternoon. Buzard said he wasn’t sure of the volume of guests at the time of the incident.Water is a great conductor of electricity, Meola said."It’s definitely the one place you don’t want to be during a storm," she added.Two other people in the immediate area at Beltzville were also injured.Officials did not release their identity or condition Sunday. Looking aheadAccuWeather meteorologists predict a cooler, dry Monday with a high of 89 degrees.More storms could be on the way Tuesday, however, as there is a 60 percent chance of thunderstorms throughout the day and night.Around a half-inch of rain is predicted.
