The Coral Spawning Outlook

The August full moon occurred Saturday evening. Historically, the best time to observe coral spawning in the Bay Islands has been, the 3rd or 4^th nights, after the full moon. This week, plan on night diving, Tuesday through Friday nights, between 9:00pm and 2:00am. Monitor the tidal schedule, as spawning usually occurs in conjunction with the evening's high tide. Tonight high tide is around 9:30pm. (see Fig 2)

On day dives, look for engorged or enlarged coral polyps in the hard corals and mass spooring from the sponges. A high degree of polyp enlargement or visibly emerging eggs in the polyps, is a good indicator that spawning is imminent.

The Tropical Weather Outlook

TS Gert is expected to pass Bermuda today. An area of disturbed weather designated 92L is about 450 miles NNE of the northern Leeward Islands. It is expected to follow a track very similar to Gert. Neither of these storms pose a threat to the Bay Islands. 93L, now has a 20% chance of strengthening in the next 24 hours.(See Fig 3)  This morning it was traveling W at 15 to 20 mph and is about 1800 ESE of us. Further development if any, will be slow to occur. However, because this disturbance is ESE of us, all interests in the Bay Islands should continue to monitor its progress. (See Fig 4)
