Severe thunderstorms rolled through parts of North Florida on Saturday morning. The National Weather Service (NWS) in Jacksonville announced tornado warnings for parts of Putnam and St. Johns counties. There were reports that a tornado touched down near St. Augustine.
The Weather Channel says forecast models suggest the low-pressure system will move up the Eastern Seaboard through the weekend. The storm is expected to intensify and race up to eastern Canada by Sunday morning.
Models indicate the storm could be classified as a bombogenesis, a weather term that describes how a storm's central pressures falls 24 millibars within 24 hours, by late Saturday.
The storm will be a rain and wind event for the Northeast on Saturday and early Sunday. The heaviest rain will be seen on Saturday.
Rain is expected to change into heavy wet snow in the eastern Great Lakes and the Appalachians on Saturday evening.
