More rain, lower temperatures, and clouds!
This system of storms that has been sitting over Fiji will persist throughout today. The cloud cover and rainfall has lessened as of recently, but is still significant. There are two pictures below from MTSAT mixed IR/Visible satellite retrievals, the first is from 8:00 pm, and the second from 3:00 am.
Cloud cover weakening as the night goes on and the earth cools is not an unfamiliar process, however what is seen above is also indicative of part of the storm system moving on. This may be better seen from a zoomed out version of the same above two images shown below.
Current rainfall radar (click to watch it loop) shows modest activity over all of the islands, with the most rainfall over the oceans just to the east.
The atmospheric sounding (below) shows a deep moist layer, 42 mm of precipitable water (~1.5 inches), and surface temperatures at around 20˚C (70˚F).
Winds at the surface are low, but increase rapidly with altitude.
