 And here in Maine, Acadia National Park officials are encouraging visitors to prepare for hot weather as they visit during the long holiday weekend. But it's so important to not underestimate the heat here. Our trails, a lot of them, they go straight up and you can be exerting a lot of energy going up them. It's Thursday, July 4th. We'll see some rain showers in southern Maine today, but we should have mostly pleasant weather further north. World and National News is next.
