GULF OF MEXICO SITE SPECIFIC SUMMARY DATE: SATURDAY OCT 8 2011 TIME: 800 CDT GULF OF MEXICO SUMMARY FOR DEEPWATER LEASES: High pressure over the eastern US combined with a broad area of low pressure over the northwestern Caribbean will allow strong easterly winds to persist over the leases today.

The low will be monitored for any signs of development. EXTENDED OUTLOOK: Winds are expected to decrease on Tuesday and Wednesday as a weak cold front moves through the Gulf. Models indicate a second weak cold front to move into the Gulf on Friday. FORECAST CONFIDENCE: MARGINAL SEVERE WEATHER OUTLOOK FOR DEEPWATER LEASES: Isolated to scattered showers and thunderstorms are expected to continue over the Gulf today.
