Hurricane forecasters tracking more tropical trouble as Atlantic Basin bubbles with activity
Erin remains the captain of the map, but its time as a hurricane is fast running short, as it begins to transition into a non-tropical North Atlantic storm and races away from the Canadian coast.
Hurricane Hunters set to investigate Invest 90L in Atlantic
With Hurricane Erin moving away from the U.S., attention doesn't turn away from the tropics in the Atlantic. The NHC is monitoring Invests 90L and 99L for tropical development. The Hurricane Hunters are set to fly into 90L on Saturday.
MIAMI – The Atlantic Ocean remains busy with a few tropical troublemakers, but now that Erin is fast leaving the picture, it doesn't appear the tropics will be very bothersome anytime soon.
Outside of the remnants of Erin, forecasters are still keeping eyes on two other systems farther out in the Atlantic that could have inklings of developing into their own named storms.

Invest 90L on the cusp of graduating
The system with the greatest odds of eventually becoming at least a tropical depression, if not Tropical Storm Fernand, is cluster of showers and thunderstorms around a trough of low pressure about 250 miles northeast of the Leeward Islands. The NHC designated this system as Invest 90L late Thursday morning, allowing forecasters to run additional computer models runs to track the disturbance.
This disturbance continues to show signs of organization and the NHC is giving near certain odds it'll develop into a tropical depression or Fernand over the weekend while it moves near or to the north of the northern Leeward Islands.

Whatever 90L turns into, it looks to steer well clear of the U.S. coast, but could bring some impacts to Bermuda.
"Interests in Bermuda should monitor the progress of this system as watches or warnings could be required on Saturday," the NHC said in their Friday afternoon tropics update.
Invest 99L: Dawdling in the central Atlantic
Meanwhile, the tropical wave that has been tagged as Invest 99L as it now tracks about halfway between Africa and the Caribbean's Windward Islands remains rather disorganized, the NHC said. And unlike Erin and 90L, Invest 99L's prospects for a long life are dim.

Invest 99L is fighting atmospheric conditions that are only marginally favorable for development over the next day or so as it journeys west-southwestward. But with more hostile atmospheric conditions looming on the path ahead, the NHC said a short-lived tropical depression is about the ceiling for its development.
If, by chance, the system manages to squeeze out enough development to reach tropical storm status, it would take the name Gabrielle (provided that other storm takes "Fernand" first.)
Officially, the NHC is maintaining a low chance for development, but the odds have dropped.
A third batch of thunderstorms the NHC was monitoring farther to the north in between 90L and 99L essentially fell apart Thursday night and has since come off the tropics map.
