Just a guess at this point, but its certainly possible that Lili could threaten Florida next weekend - perhaps as a Cat III. Tough call on Puerto Rico - maybe near the northeast tip of the island Wednesday afternoon - but thats still a long way down the road. If you want to see a possible analog track (not for intensity, just for track) check out storm #4 in 1928. Could have three hurricanes in the basin next week - been a long time since we've seen that.
Cheers,
