As seen on a sequence of 3-hourly GOES-15 (GOES-West) 6.5 µm water vapor images with satellite-derived atmospheric motion vector (AMV) winds from the CIMSS Tropical Cyclones site (above), a weak but persistent trough aloft over the Hawai’i region was acting to destabilize the atmosphere and create an environment conducive to the development of widespread showers and thunderstorms — some of which were producing heavy downpours over parts of the island chain — during the 04-05 November 2014 period.

Due to radar outages, the NWS forecast office in Honolulu HI requested that the GOES-15 satellite be placed into Rapid Scan Operations (RSO) mode (NOAA/NESDIS bulletin), providing 10 images per hour (compared to only 4 per hour during routine operations). An animation of GOES-15 0.63 µm visible channel images (below; click image to play animation) begins at 17:30 UTC with routine 15-minute interval images, and then after 21:30 UTC transitions into the RSO images to demonstrate how the development and motion of features can be more carefully monitored with improved temporal resolution.

    I’m just glad we were actually able to *get* the rapid scan over Hawaii. Took some…focused coordination & clarification…to actually make it happen.
