NHC has upgraded Invest 97L to Tropical Storm Nana.

A large portion of the cyclone's circulation continues to be exposed, having been continuously battered by shearing winds from the west. Nonetheless, NHC expects Nana to sustain for a couple more advisories before finally giving up the ghost and degenerating into a remnant low. Nana is not expected to pose any threats to land.

The center of Invest 98L recently passed very near a buoy in the eastern Caribbean. Pressures dropped to around 1006mb, and winds at that location increased to 27 knots (about 30mph sustained), gusting to about 35mph. 98L continues to get better organized today, and it is becoming obvious that another October tropical cyclone is developing.
