Fire crews on both coasts of the U.S. continued battling wildfires Sunday, including one in New York and New Jersey that killed a parks employee.

The first measurable rainfall over New Jersey in weeks raised hopes on Monday of snuffing out a rash of wildfires that has plagued the state, while stronger winds brought concern that a California blaze that had already destroyed dozens of structures could start expanding again.

Firefighters are currently battling the Jennings Creek wildfire in Sterling Forest State Park on the border between the US states of New York and New Jersey. A young state forest ranger died during the firefighting efforts on Saturday.
