We continue to follow a disturbance dubbed Invest 94L tracking westward through the central Atlantic. Though not unheard of, the almost due-west course from the deep tropical Atlantic is an unusual trajectory for a system this late in the season, when developing systems most often turn quickly north and east once they're in the vicinity of the Caribbean.
Although the development zone appears threatening for the mainland U.S. at first glance, 94L will fall short of posing any problems for us stateside next week as it encounters a firehose of wind shear guarding U.S. shorelines, courtesy of reinforcing fall cold fronts.
If 94L becomes a Tropical Depression or Nadine over the next few days, models show it either dropping southward and weakening through the Windward Passage between Cuba and Hispaniola or getting torn up and flung out to sea and away from the U.S.
Either way, 94L isn't expected to make it very far before succumbing to the winds of climatology.
Rainmaker for the Greater AntillesAs we mentioned in yesterday's newsletter, because the low-pressure circulation is well-established, it wouldn't take much additional organization to its thunderstorms for 94L to get upgraded to a tropical depression or Tropical Storm Nadine.
