Heavy fog that had shrouded Long Island for a second straight day started to burn off Tuesday morning, but a dense fog advisory remained in effect for coastal waters until Wednesday morning.

A dense fog advisory for land areas was lifted at 10 a.m., but it might be renewed if weather patterns change, according to Lauren Nash, a meteorologist with the National Weather Service in Upton.

As it did Monday, the weather service had issued a dense fog advisory, advising drivers to "slow down" because of poor visibility created by fog conditions.

The weather service said it issues such advisories when visibilities are reduced to one-quarter mile or less by fog.

There were no reported delays at Kennedy and LaGuardia airports due to the weather, according to the Federal Aviation Administration website.

Long Islanders can expect partly sunny skies and temperatures rising into the high 70s with a chance of showers and thunderstorms before 8 p.m.

Patchy fog is expected to return after midnight, with showers and thunderstorms possible again on Wednesday, and rain and fog again possible Wednesday night into Thursday.
