SummaryÖExpect a wide variety of conditions into next week with very rough
seas S-SE of South
Africa
1) Gale is centered near 44s/11w at 12 utc Wed and moving ESE.
2) Your NNE winds at 12 utc will back to N then NW ahead of the associated
cold front in the next 12-
18 hours.
3) Wind speeds mostly in the 25-35 kt range but there could be some winds
over 40 kts especially in
developing squalls as the front gets closer.
4) Expect the front to move thru around 12 utc Thu with winds shifting to
W-WSW and slowly
diminishing.
5) High pressure following the front will be near 40s/5w at 12 utc Fri and
will track to near 42 30s/14
30e by 12 utc Sat..
6) As the high approaches your winds will continue to back into the S then
SE by 12 utc Sat.
a) Wind speeds come down 10 kts or less Saturday.
7) Then as the high moves E of you, your winds will continue to back into
the E then NE and increase
to 25-30+ kts by Sunday night .
8) Monday winds may trend more northerly depending on how fast a cold front
approaches from the W
a) This will force you eastward south of the main portion
of the Agulhas current.
9) Sea state is going to become an increasing concern as it builds with the
front next 24 hours.
10) But more so over the weekend as wave model shows a large SW swell
arriving from W to E.
11) This swell could reach 14-20 ft Sat then diminish a little Sun/Mon.
12) But it will become very rough with confused sea state then as winds
become NE
RoutingÖ Not many changes next few days
Once you get the frontal passage and the wind shift to the
WSW go onto starboard and ok
to head ESE Thu/Fri
But need to be careful you do not get into the center of
the high on Sat.
Expect as high approaches from the W and winds back thru SE
you will get forced NE Sat.
As winds back to NE Sunday you will be back on port and
heading ESE-E early next week
S of the main portion of the Agulhas current.
Our route keeps you S of 40s thru Monday. Estimated
