Looking Ahead

An unsettled trade wind weather pattern is forecast to continue through Wednesday. Big Island is still under a Flash Flood Watch due to the wet weather conditions. The potential for locally heavy rainfall still exists. Afternoon convection is also a possibility today with trades being light enough for these to develop for interior and leeward locations. A drier and more stable trade wind weather regime is expected to return late in the week.
