Daily Weather Forecast Mirai Updates! Nauru Updates!

Commentary:

Overnight we moved to north of the island, but winds shifted from northeasterly to southeasterly. This caused us to move again this morning to the east side of the island, again 2 km offshore, directly upwind of the Atmosphere Radiation and Cloud Station (ARCS) on the west side. Two strong squalls passed the ship before noon. The first caught Ed Westwater in the RHIB (small boat) midway between Nauru and the ship. He got pretty wet but luckily had his suitcase in a plastic bag. Jeff Otten made it to Fiji, but his luggage did not. Earliest hope of seeing it in Nauru is 3 days hence. We hope to see Jeff tonight. Too bad we didn't have today's storms when the Mirai was nearby - they were perfect for dual Doppler.
