Lingering light showers and wind gusts of 20 to 30 mph were all that were left Friday afternoon of a storm that swept across Long Island.

For much of the day, the Long Island Rail Road reported scattered systemwide delays of 10 to 15 minutes due to "slip-slide" conditions -- where train wheels slip while accelerating or slide during braking.

But just 0.04 of an inch of rain was recorded at Long Island MacArthur Airport in Ronkonkoma and 0.06 in Upton, said Tim Morrin, National Weather Service meteorologist.

A severe thunderstorm warning had been issued for southern Nassau County in the early morning hours. Gusts of 50 mph or more were reported, with the strongest winds along the southern coast, but Long Island power outages were minimal, officials said.. In Manhattan, four people, including a firefighter, were taken to hospitals with apparently minor injuries after high winds caused a covering from a business to fall, an FDNY spokesman said. The incident occurred shortly after 10 a.m. at Seventh Avenue and West 39th Street.

Temperatures, which had been expected to reach 70, stayed in the mid-60s, Morrin said, with 65 reported at MacArthur Airport at about 11 a.m. Mostly sunny skies, with a high temperature of 65, are forecast for Saturday, Morrin said
