The southerly Kona wind flow continues to bring up hot and humid air for the deeper tropics.
The weak low level trough has stalled near Kauai and Niihau helping to trigger deeper convection and thunderstorms over both islands this evening.
A Flash Flood Watch remains in effect trough early Wednesday morning over Kauai and Niihau. Thunderstorms remain possible along this trough axis tonight, and over the Big Island interior on both Wednesday and Thursday afternoons.
The potential for heavy rain showers will gradually diminish over the next 48 hours as this low center continues to drift northward decreasing the dynamic lift along the low level trough.
