A closer view using 5-minute PACUS Sector GOES-18 Infrared images (below)<\/strong><\/em> included 15-minute METAR plots — which showed periodic moderate to heavy rain; Local Storm Reports<\/strong><\/a> mentioned some flooding (and wind damage).<\/p>\n

Of note was the issuance of a Tornado Warning<\/strong><\/a> at 0515 UTC on 09 January for the far western portion of Molokai island (below)<\/strong><\/em>.<\/p>\n

Microwave estimates of Rain Rate (derived using the MiRS algorithm within the CSPP software package) are available at this website<\/a>. The animation below shows seven observations on 8 January 2024, from 07 UTC to 23 UTC. The axis of the heaviest rain was over Oahu starting at 1900 UTC on 8 January.<\/p>\n\n\n\n
