Fall arrived on Long Island Tuesday with the easing of a late-season cold snap and the promise of warmer weather ahead.

After a series of colder-than-normal days marking the end of summer, temperatures will rise to the 70s Wednesday, forecasters say, and sunny, dry conditions will dominate until Sunday.

After Tuesday’s daytime high finally hit the 70-degree mark, Wednesday was expected to jump into the high 70s and daytime temperatures will remain in the low- to mid-70s on Long Island all week, forecasters said.

Wednesday was also expected to be breezy and the continuing dry weather has prompted the National Weather Service to warn of ideal conditions for wildfires to start.

As Hurricane Teddy makes its way to Nova Scotia and Newfoundland in the next couple of days, Long Islanders may see some effects, though the storm should stay out in the Atlantic Ocean and weaken as it hits cooler waters, experts said.

On Wednesday, there is a coastal flood advisory from noon to 4 p.m., the weather service said.

For both Nassau and Suffolk, a high surf advisory runs until 6 a.m. Wednesday, and there is a high risk of rip currents through Wednesday evening.

"Significant and widespread erosion and damage to dune structures" was expected Tuesday night, along with "minor to moderate flooding" in low-lying areas, the weather service said.

The odds of the next downpours arriving are 40% on Sunday night and 30% on Monday, the weather service said.

A high near 73 degrees is expected Monday.
