(BIVN) – A band of deep moisture will move over the eastern half of the state and stall through Tuesday, the National Weather Service says, as it issued a Flash Flood Watch and Winter Storm Warning for the Big Island starting at 6 p.m. Monday evening.

“Convective showers within this band will likely trigger heavy rainfall and thunderstorms over the Big Island and Maui County,” forecasters wrote. “This band is expected to move eastward Tuesday night and Wednesday, though this Flash Flood Watch may need to be extended if heavy rains linger.”

The band of moisture will also produce “periods of heavy snow later this evening and lasting through Tuesday night,” the National Weather Service stated. “Unlike recent events, snow levels start above the 11,000 foot elevation level,” forecasters added.

Total snow accumulations of 5 to 10 inches are possible on Mauna Kea and Mauna Loa. The road to the summit of Mauna Kea is closed.
