Idalia is moving toward the east near 9 mph (15 km/h), and this 
general motion is expected to continue through the day.  A faster 
northeastward motion is forecast to begin on Sunday, followed by a

Little change in strength is forecast during the next few days.

sustained winds of 57 mph (91 km/h) and a gust to 68 mph (109 km/h).
