...Tropical Depression Moke passing south of the Islands...



Passage today of Tropical Depression Moke several hundred miles 

to the south of the islands favors lingering strong gusty winds 

over the state within tightened pressure gradients between surface

high pressure north of the state. A deep plume of moisture north 

of Moke will fuel additional rainfall. With Moke rains coming 

quickly on the heels of Lala, life-threatening flooding and 

mudslides remain a concern. Even as the system continues west and

weakens, guidance shows an elongated stretch of deeper moisture 

may remain across the islands, potentially yielding local 

downpours into Tuesday. Guidance agrees to show drier conditions 

with a return to more typical easterly trades with a limited 

windward terrain focusing showers pattern the rest of the week.
