A 16-hour animation using 5-minute GOES-18 PACUS imagery, above (saved from the Geosphere site) shows persistent convection along the east coast of Oahu on 13 May. MIMIC estimates of Total Precipitable Water on 13 May, below, show the state of Hawai’i surounded by abundant moisture, although the richest moisture within the... Read More
1-minute Mesoscale Domain Sector GOES-18 (GOES-West) “Clean” Infrared Window (10.3 µm) images (above) displayed a period of convective bursts near and over the American Samoa island of Tutuila on 04 February 2024 — which produced heavy rainfall (leading to flash flooding and landslides; during the 6-hour period ending at 1200 UTC, Pago Pago...

The Night Microphysics RGB animation below, taken from the CSPP Geosphere website (direct link to animation) shows strong convection over the central Gulf of Mexico along with cloud conditions in the surrounding states. Note, for example, the expanding region of low clouds over Texas. The annotated images below (0216, 0646 and 1046 UTC) highlight... Read More
As discussed in this blog post, heavy rainfall had continued across the Samoan Islands on 25 December 2023. The South Pacific Convergence Zone (SPCZ) remained in the vicinity of the Samoan Islands on that day (surface analyses) — and 1-minute Mesoscale Domain Sector GOES-18 (GOES-West) “Clean” Infrared Window (10.3 µm) images (above) showed additional pulses of deep convection that...
