Tropical Storm Moke formed Friday in the central Pacific with maximum sustained winds of 45 mph and a minimum central pressure of 1,002 millibars., according to the National Hurricane Center (NHC).
Formerly known as Tropical Depression Two-C, Tropical Storm Moke is located about 660 miles southeast of Hilo, Hawaii, moving west-northwest at 9 mph.
A Flood Watch is in effect for the Big Island as heavy rain from Moke threatens dangerous rainfall rates, coming on the heels of Hurricane Lala.
A tropical storm is a tropical cyclone with maximum sustained winds of 39 to 73 mph, making it stronger than a tropical depression.
Since Moke is forecast to remain a compact storm, the NHC said no tropical storm watches or warnings are currently required based on its forecast track. However, that doesn’t mean Hawaii won’t see impacts from wind, heavy rain and dangerous surf.
Hawaii, which rarely sees tropical activity, will face its second tropical system in less than two weeks with Tropical Storm Moke expected to dump another round of heavy rain on the Big Island, in particular, as well as other islands across the state.
