While the exact cause of the brush fires remains unclear, authorities were quick to point out that there wasn’t any lightning in the region at the time, leaving only human causes as the primary source.

According to Cotton, an arson investigation is now underway. However, it's still too soon to say whether the fires were intentionally set.

Fortunately, due to the stiff northwesterly winds, smoke was largely carried offshore over the Atlantic Ocean, leading to few air quality concerns across the New York City metro.

Some of the smoke plumes were large enough to be seen on radar, with returns indicating that the some and ask were billowing over the Atlantic.

Official said that the mission on Sunday was to achieve 100% containment of the fires on Long Island, which have burned at least 600 acres in Westhampton, New York.

"There are hotspots being addressed in Eastport right now, but no visible fire in Westhampton per ground crews," Southampton Public Safety and Emergency Management Administrator Ryan Murphy said. "Aviation assets are going up right now to to a better check."

Murphy said the fire was about 80% contained as of Saturday night.

The Empire State is not the only state grappling with brush fires; large swaths of the mid-Atlantic and Southeast have had similar bouts with flames.

The combination of dry vegetation, an intensifying drought and gusty winds has created an environment ripe for wildfires along the eastern seaboard, from southern New England through Florida.

Many communities in the region are experiencing conditions that range from "abnormally dry" to "extreme," which enhances the amount of vegetation available to fuel fires.

Meteorologists expect winds around the tri-state to remain elevated through the weekend, but moisture will return in the form of scattered rain showers on Sunday and higher humidity levels during the workweek.

The increased moisture should help firefighters gain a better handle on any uncontrolled fires and limit potential issues with smoke along Long Island.
