GULF OF MEXICO SITE SPECIFIC SUMMARY
   DATE:    FRIDAY  MAR  12 2010 TIME:    800   CST
                                                                                                                                        
   GULF OF MEXICO SUMMARY FOR DEEPWATER LEASES:
   Strong north to northwest winds will continue to spread across the leases behind a cold
   front that is currently moving east over the central Gulf. Winds become more westerly
   tonight and tomorrow, while steadily weakening, as high pressure moves into the southern
   Gulf. A second high pressure system will then begin to move into the central US, allowing
   for light north to northeast winds Sunday.
   
   EXTENDED OUTLOOK:
   Light to moderate northeast winds continue Monday then shift to the north and increase
   Tuesday as a low pressure system and cold front develop over the southern Gulf. North
   winds are expected to decrease Wednesday as the low exits the Gulf. Models indicate south
   to southeast winds to return Thursday and Friday.
   FORECAST CONFIDENCE: FAIR/MARGINAL
 
   SEVERE WEATHER OUTLOOK FOR DEEPWATER LEASES:
   Showers and thunderstorms will continue to develop over the eastern leases today. Some
   activity may spread into the central leases. Winds and seas will be higher in and around
   any of the stronger storms.
   
 
   TROPICAL WEATHER OUTLOOK:
   Tropical development is not expected.
