Marianas synopsis... 
a TUTT passes east of the marianas along 150e. An approaching 
trade-wind disturbance just to the southeast of the forecast 
zones has all but dissipated. A much more substantial trade-wind 
disturbance lies over and to the north of Chuuk and Pohnpei. Much 
smaller and weaker trade-wind disturbances can be seen on 
satellite southwest of Wake Island. 


satellite trends and near term model guidance both suggest the 
bulk of the trade-wind disturbance and surge currently north of 
Chuuk and Pohnpei will pass to the south of Guam. System remains 
diffuse enough to suggest scattered shower coverage is not in the 
offing for Guam tonight or Sunday...but situation will have to be 
monitored. After this disturbance passes...follow on trade-wind 
disturbances will continue supplying low-level moisture through 
Tuesday. TUTT will be lingering in the will carry 
mostly cloudy skies and isolated thunder in the forecast tonight 
through Tuesday. Second half of the forecast period looks drier 
as trade-winds usher in a drier air mass. 


latest altimetry and buoy readings initialize combined seas 
closely to gridded values between 6 and 7 feet. 
arriving at the buoys is more concentrated in north swell versus 
east bumped up north swell 2 feet and shaved a foot 
from east swell today and tonight. Change results in a 5-foot 
north swell...which is only a foot or so below the height 
necessary to generate high surf. Wave watch guidance suggests 
north swell have already do not believe high surf is 
likely during the next couple of days. Winds were gusting to 
around 25 knots earlier this morning over the forecast zones but 
have decreased this afternoon. Low pressure developing south of 
Japan will be weakening the subtropical ridge during the next 
couple of do not anticipate a Small Craft Advisory for 
winds either. 


Eastern micronesia... 
a fresh to strong trade-wind surge is moving through the region 
this afternoon. The leading edge of the surge is just north of 
Pohnpei to just south of Kosrae. Scattered showers that were 
expected this afternoon at Kosrae did not materialize with most 
of the convection developing late and to the south of 
Kosrae...though isolated showers and thunderstorms do remain a 
possibility there through the evening as the surge continues to 
push westward. Scattered showers are now moving into Pohnpei 
waters and are expected to continue there until around midnight. 
A secondary surge is now moving in to the Marshall Islands... 
bringing another round of isolated showers and thunderstorms to 
Majuro. These showers are expected to move west of Majuro late 
this evening with a brief period of drier conditions moving 
through the region through Sunday night. A trade-wind convergence 
zone is now just east of the date line and is expected to move 
over the Marshalls early Monday and spread over Kosrae Sunday 
night and over Pohnpei Monday. This convergence will maintain 
unsettled conditions over Majuro until the end of the week. As 
winds weaken over Kosrae and Pohnpei by midweek...the convergence 
zone will begin to dissipate. This will allow drier conditions to 
set up over both locations Wednesday. 

Building trade-wind swells and wind waves will cause higher surf 
and rip current risks along the east facing shores of Kosrae 
state and the Marshall Islands during the next few days. heights for both places should stay below 
hazardous levels. 


Western micronesia... 
a weak disturbance is moving through Chuuk this afternoon... 
bringing scattered showers to the state a little earlier than 
previously expected. The leading edge of a trade- wind surge will 
move into the state Sunday...maintaining scattered showers over 
weno through the day. Showers will quickly decrease over the state 
Sunday afternoon with drier conditions likely for a brief period 
Sunday night. For Monday...the trade- wind convergence pattern 
that will affect Pohnpei will likely bring another round of 
unsettled weather to Chuuk early next week. 

Dry conditions are expected to continue over Yap and Koror though 
Sunday night. Early next week...increasing trade-wind convergence 
will bring an increase in convection to the region. Most of the 
activity will remain north of Koror though isolated thunderstorms 
are a possibility....especially over the northern coastal waters. 


Gum watches/warnings/advisories... 
Marianas waters...none.
