first off, to LIPhil, hope you get better soon

now for the Caribbean system, it is interesting to note that we have not had a tropical storm in May since 1981 (which i think is the longest time period in the satellite and radar era); and it is only a matter of time before we have another. The low east of Honduras does seem to be forming a circulation, and there is a feeder band comming into the SE edge from the Pacific (usually a good indication of formation).
Not going to say yet if I think it will develop, but it looks like the best possibility since the system in 1996 (last year's low was subtropical)

it is also interesting that the last May storm was Arlene
which will be the first storm this year
