There is wide spread rainfall across Fiji right now. The rates are reaching as high as 50 mm/hr (nearly 2 inches per hour).

This downpour should continue throughout much of the day.

The colorized infrared satellite imagery depicts deep moisture over the islands, and full cloud cover. Given what the rainfall radar looks like, imagery like this is to be expected.

The vertical atmospheric sounding shows a moist atmosphere, with  62.96 mm (nearly 2.5 inches) of precipitable water. Winds aloft are out of the west, and moderate. They could conceivably push the rainfall through the islands by later today, though not before a lot of rain falls.

The sea level analysis shows a major culprit behind today’s activity is a low pressure center just to the south of the islands. It is bringing the associated rain and clouds, and should provide better air quality conditions.
