Long Island’s dry spell may soon end, although the region will remain under a red flag until 6 p.m. Saturday, the National Weather Service said.

The alert is a combination of low humidity of 25% in the area and wind gusts expected to reach up to 30 mph throughout the afternoon, the weather service said.

“Those are two conditions that are considered there (on Long Island) to have the potential to spread wildfires if they were to start,” said NWS meteorologist David Stark. “If a fire were to break out, conditions could cause it to start very quickly.”

Winds are expected to ease Saturday evening, Stark said, and rain is forecast Sunday evening.

“This may be the first wet, measurable rain we’ve seen here, more than just a little bit in the last couple of months,” Stark said.

There will also be a Freeze Warning on Long Island, in effect from 10 p.m. Saturday until 9 a.m. Sunday. Temperatures are expected to drop as low as 29 degrees, which could pose a danger to some crops.

“It’s more for the agricultural side. It’s not the type of gel you need to protect the pipes,” Stark said. “If you have sensitive plants outside that a frost could potentially kill, they obviously need to be protected.”
