The tropics still have something to say this season. Tropical Storm Sebastian formed today east-northeast of the Leeward Islands. The storm is expected to stay over open waters. It is also encountering conditions that are hindering its development.

"The low-level center of Sebastian has been exposed over the past several hours, as northwesterly shear of 20-30 kt has been pushing any deep convection off to the southeastern portion of the cyclone," said Hurricane Specialist Andrew Latto at the National Hurricane Center. "The shear is not expected to decrease much over the next couple days while the system remains a tropical cyclone."

Sebastian is currently moving northwest, but the long range forecast has Sebastian turning north then northeast, staying out to sea before becoming extratropical, then getting absorbed by a cold front late this week.
