We're in the middle of an absolutely beautiful stretch of weather that continues through Saturday. Meanwhile, in the Gulf, Hurricane Isaias has become the first hurricane of the Atlantic Hurricane season, the latest on records. It will make landfall on Friday on the Gulf coast and the remnants will bring rain to Long Island late Sunday into Monday. Track the Tropics on News 12's new tropical weather page here.

TODAY: Warm and Breezy

Grab the sunglasses, it's a beautiful day. Ample sunshine is expected with temperatures climbing into the mid 70s. It is breezy with wind gusts occasionally reaching 20-25 mph. A Small Craft Advisory is in effect for portions of the south shore because of the wind.

FRIDAY: Sunshine Returns

It's another great looking day with temperatures near 50-degrees in the morning and near 70-degrees in the afternoon. The wind is light in the morning but increase to 15 mph from the west in the afternoon.

Rain returns Sunday & Monday

Isaias (ees-ah-EE-ahs) is churning and strengthening in the Gulf. This storm is important to Long Island because the remnant moisture in the form of steady rain from this will reach the island late Sunday through early Monday.
This will not be an organized storm and major impacts are not expected for Long Island. However, with up to 1" of rain expected, there wil be impacts to fall festivities and travel plans late Sunday evening through Monday morning. A reasonable worst case scenario would be wet weather all afternoon Sunday and through Monday, but at this time the rain looks limited to late Sunday and Monday morning.
The News 12 Storm Watch Team will keep you updated on this through the week.
