SummaryÖ Lighter winds next 24-36 hours ñ be careful about too much easting.
1) High pressure is located near 33s/90e and will stretch out W-E and lift
up to 31-32s by 12 utc Thu.
2) Still need to be careful about getting sucked into the high so as winds
back into the N and NW limit
easting.
3) When winds go past 330 then head S on starboard ñ this should keep you
just east of the < 10 kt
winds and also into increasing NW winds earlier by 12 utc Thu as
frontal system passes by to your
S.
4) This first front will bypass you but latest guidance has low pressure
tracking ESE to near 40s/75e by
12 utc Friday.
5) This low will be just to your W 12 utc Fri and pass to your SE by 12 utc
Saturday with associated
frontal boundary approaching from the W.
6) This will lead to increasing NW winds ahead of the front by 18 utc Fri
and could get to 25-35 kts
with squalls to 40 kts on Saturday.
7) You will be heading fast to the E then and will stay ahead of the front
so it may not catch you until 12
utc Sun.
8) This is a change in the weather pattern from yesterday with no second
high coming in behind the first
front.
9) If correct then you may not have to get as far south as indicated
yesterday.
10) We will have more confidence on that as we get closer.
RoutingÖ You may not have to get as far S as it looked yesterday but
still need to be careful about
getting sucked into the high next 48 hours.
As winds back head SE but when they get left of 330
gybe to starboard and head S to
avoid lighter air to E
Get S to around 39-40s then head E on port ñ we can
adjust this over the next few days
But looks now like you do not need to get as far S to
be in good winds over the weekend.
