Southwest winds of 25 to 35 mph with gusts up to 50 mph, especially in the higher elevations, for the next couple of days. Winds will then gradually normalize. ...COASTAL INUNDATION AND SURF INFORMATION... Coastal inundation is not expected from Tropical Depression Krosa. Due in large part to the monsoon flow heading into Krosa, hazardous surf of 8 to 11 feet will continue the next couple of days then slowly diminish. ...OTHER STORM EFFECTS... A Flood Watch is in effect for the entire area. Heavy rains will build in by afternoon. This very wet monsoon flow will continue through Saturday night, dropping a total of 4 to 8 inches of rain.

Residents should keep aware of the latest trends regarding TD 12W. The latest track depicts a passage to the west of the islands with tropical storm conditions possible by midday. Preparations should focus on securing loose items with anticipation for southerly tropical storm winds of up to 50 mph. .WIND INFORMATION... The latest forecast track shows Krosa moving generally northward through Saturday, then turn slightly to the north-northeast on Sunday, but staying west of the islands. This will cause southeast winds to shift to south and increase today, becoming increasingly gusty as more widespread showers arrive today. Latest forecast projections show south tropical storm winds of 35 to 40 mph possibly arriving by this afternoon and gradually shifting to southwest Saturday, before diminishing sometime Sunday. Even then, a strong southwest monsoon pattern will prolong windy conditions through Sunday night. .COASTAL INUNDATION AND SURF INFORMATION... Surf will initially rise along south facing reefs today, then spread to west facing reefs Saturday, exceeding hazardous levels of 9 ft. Surf along these windward shores could approach dangerous levels of 15 ft Saturday and Sunday and remain at hazardous levels of 10 to 14 ft into early next week due to the persistent monsoon flow. Rip currents during this time will be strong and life threatening. Stay out of the water. Minor wind and wave-driven coastal inundation of up to 1 foot will be possible along windward shores, especially around times of high tide as surf reaches peak heights Saturday and Sunday. .OTHER STORM EFFECTS... Scattered showers will increase beginning around midday, becoming locally heavy Saturday and Sunday as 12W passes to the west. Rainfall amounts of 6 to 10 inches are possible through Monday. Even after Krosa begins to move away Sunday and Monday, a wet monsoon pattern will prolong showers across the islands. $$ Stanko
