nothing of any significance here so far.

1200z VRBL F1-2 15km -RA RETS 4St006 6Ns050 14.1/12.9
1009
RMK: Continuous thunder and lightning 1000z-1130z. Mostly to the SW
but
one brilliant flash and almost simultaneous crack of
thunder. The
heaviest of the rain has stayed just to the SW though we
have had
occasional heavy bursts. Mostly, though, it's just been
slight to mod.
Davis VP says 14.7 mm since 00z so not a notable event here.
I suspect
it's very different not very far to the SW. Much brighter to
the S now so
it looks as if the event is coming to an end here.
