* ADDITIONAL DETAILS...Typhoon Bavi (09W) and the trailing monsoon
surge will continue to produce significant swells towards the
Marianas. Dangerous surf heights of up to 20 ft and coastal
inundation of 1 to 3 ft can be expected through at least
tonight, especially along west-facing shores. A local observer
reports 15 to 18 ft at Oka point. Then, surf will gradually
diminish as Bavi moves farther away. South and west facing
shores are expected to see the highest surf. Huge waves are
producing deadly rip currents through at least Wednesday night.
Everyone should remain out of the water due to life-threatening
surf conditions. Stay off of jetties, piers, and other waterside
infrastructure.
