Grenada Update
Ophelia and UARS.

Ophelia is still disorganised with dry air between us and it,
causing it problems. It's path has dropped a little with more
predictions bringing it nearer to Antigua.
But most have it passing safely to the NE.
Not weather related, but:
The UARS satellite that you have probably heard is 'crashing to
earth' probably today, is doing one pass over the Eastern Caribbean
at about 18:15-18:25 this evening (as it is getting lower it's orbit
changes so difficult to make an exact prediction). But it is just
possible that it could chose this orbit to come down, in which case
it will be quite spectacular. At the moment, Antigua area will be
about the best place to see it. I stress that in the still bright
sky, at this time, it will only be easily visible if it happens to
be burning up. If it has started to enter the atmosphere earlier,
then crash helmets might be a good idea. From Grenada you will have
to look very low to the west to North West. The chances are very
low, but you never know.
A graph showing it's decaying orbit (Height), over the last week.
The heights are in kilometres and the green one is just an arbitrary
height that I chose as the point at which it cannot stay up any
longer (just a guess).
