Leslie Swipes By Bermuda, Heads For Newfoundland
Farther east, Michael continues to spin around in the Atlantic but it will likely not last much longer. Northerly wind shear will increase thanks to Leslie's large circulation and the result will be a storm that shears about. Also, the storm is being tugged west into that outflow from Leslie thanks to a ridge of high pressure building into the storm's north, so it can't escape by staying east of Leslie. The result in the coming day will be a weakening trend that also includes a gradual transition to a nontropical system, if it can survive the increasing wind shear. Given Michael's smaller size, the storm may not handle the incoming hostile environment all that well.
Elsewhere in the tropics, to Michael's southeast on the edge of the map is a large area of thunderstorms with a tropical wave. It is trying to develop a low pressure center with it as it cruises along to the west-northwest. This system may develop into Nadine over the coming couple of days but it will not impact the US. Steering in the atmosphere suggests that this will be pulled north, likely between 50 and 60 degrees longitude, with computer modeling backing up that thinking as the GFS pulls the storm to the north in three days' time.
