After losing intensity as it passes into colder waters of the Atlantic, Josephine is expected to push east of Nova Scotia, but winds and rain from the storm will still stretch inland.

00:00Now, subtropical storm Josephine, meanwhile we do have an area of concern well south of Bermuda and then way to
00:06the east as well on the horizon.
00:08It could become a tropical setup here.
00:11Meanwhile, in the east Pacific, the moisture streaming in is off to the north.
00:15We've got a tropical storm named Vance off to the south of the area of Mexico.
00:20But here's Josephine, and Josephine's drifting north at 6 miles per hour.
00:23Max sustained winds 65 miles per hour, so we went from a nor'easter to a subtropical storm.
00:30What was once part of the storm has now fractured off to the east.
00:34This was really closely tied to the fronts that were driving the organization of the nor'easter.
00:40Now this big chunk of clouds off to the east, well removed from the center of the storm,
00:44and this area of low pressure has been spinning over the relatively warm water long enough that it is a
00:49subtropical storm.
00:50So, max sustained winds again 65 miles per hour, drifting north at 6 miles per hour.
00:55Way, way offshore, we have winds producing waves that are 18, 19 feet.
01:01And then closer to the shore, we have 6 to 10 footers out there.
01:05Big waves, storms going to race to the northeast, and it will become a cold course storm in about a
01:11day.
01:11So it's only about a 24-hour window when this is a true subtropical storm.
01:16Subtropical storms have been named for about 25 years.
01:18We certainly do name more storms now than we would have with the old rulebook 40 or 50 years ago.
01:23But Josephine is on the map.
01:25And watch the wind field expand as this becomes a cold course storm.
01:30Again, a larger wind field.
01:31St. John's, Newfoundland, we can see gusts of 60-plus miles per hour there when it exits the east coast.
01:36Now, for the most part, we're forecasting 40 to 60-mile-per-hour gusts for Nova Scotia and Newfoundland and
01:42Labrador.
01:44Rainfall, eastern part of Nova Scotia, 2 to 4 inches of rain.
01:48It's going to be a fast mover.
01:49That will mitigate some of the worst of the flooding.
01:50They can handle this there in the Canadian Maritimes, an area that faces some of the fiercest storms of the
01:56western hemisphere when it comes to wind, rain, and sometimes snow.
01:59This is going to be a rainmaker there.
02:01All right, now down into the area around the mid-Atlantic coast.
02:03We still have coastal flooding.
02:04The winds have been shoving that seawater into the Chesapeake Bay and the Delaware Bay.
02:09The back bays are dealing with high water as well.
02:11It's been cumulative, and there's been, what, four days of this so far since the weekend.
02:15Now five days, and we have about a two-foot surplus in water levels for high tides and low tides.
02:21So the offshore storm, Josephine, is going to stay offshore for the most part.
02:25The only exception will be New England.
02:26A little bit of a blitz of some rain there for Newfoundland and Labrador eventually.
02:33But even in the U.S. side, we have places like Cape Cod, Martha's Vineyard, Nantucket.
02:38Just a little bit of rain, a small fraction of an inch tonight, and that'll be about it.
02:42Great weather for the interior.
