Route: Port Louis, Mauritius to Perth, Australia

Depart: approx. 0600utc, Sat, Jan 27, 2007

Prepared: 1515UTC Fri January 26, 2007

Summary:

You will need to head S for the first few days with a general E-SE wind, then you can turn towards the E as you cross 35s

• Satellite imagery indicates patchy cloudiness with scattered showers/squalls/thunderstorms from Mauritius W to Madagascar with more isolated to scattered activity to the E and SE of Mauritius
• The ITCZ has clusters of showers/thunderstorms from the Equator to aboutv10s and from 53-91e
• Computer guidance suggests a tropical low forms in this area during the weekend

a) this low would then track to the ESE or SE next week

b) will need to monitor this area during the next few days to any hints of development

• Saturday morning, high pressure will be located near 36s/56w and generally heading off to the E
• This high will keep winds mainly E or ESE with speeds in the teens for Saturday/Sunday
• Monday, computer guidance begins to have some differences with one model suggesting low pressure forms in the area bounded by 25-30s/60-65e

a) a different computer model does not develop low pressure in this area

• Have allowed for weak low pressure to develop in this area and then slide off to the ESE

a) and winds may become more SE or even SSE

b) with wind speeds up to 15-25 kts

c) if this low does not form, then winds would be more ESE or E with speeds in the teens

• In any case, winds would become more ESE or E and lighter during Tuesday as you come under the influence of high pressure ridge located to your S and SE
• You would pass thru the center of this ridge late Tuesday/early Wednesday with light and variable winds
• Once you are S of the ridge axis, SW to W winds will freshen into the teens
• Another cold front may catch and pass you mid to late week with a band of clouds and possibly some showers

a) winds shift into the S to SE behind this front

• Another high follows this front for late in the week generally movingto the E close to 40s
• Seas will generally be SW to S and vary from 5-8 ft at times up to 8-12 ft
• Would suggest getting an updated forecast in 3 or 4 days to check on the positioning of the highs and potential low developing Monday to your E

a) and also to check on potential tropical low developing

Routing:

• You will need to head S until you reach 35s since E-SE winds will not allow you to get much easting
• Eventually, you will want to be about 36-38s to avoid SE winds to the N of 35s and light winds close to 40s

a) today’s computer guidance suggests high pressure will be moving E close to 40s

• It is possible that you could turn towards the SE sooner as confidencein the longer range portion of the forecast is lower, but you will
  generally want to be around 36-38s to take advantage of more favorable winds
• Would recommend getting an updated forecast in 3-4 days to check on the weather systems and make any adjustments to your routing
• Please see waypoints listed in the wind forecast below
