154 AM ChST Wed Sep 19 2018
...HEAVY RAINFALL POSSIBLE FOR THE MARIANAS OVER THE WEEKEND INTO
EARLY NEXT WEEK...
A DEVELOPING TROPICAL DISTURBANCE AND ITS ASSOCIATED MONSOON TROUGH
WILL GRADUALLY DRIFT WEST-NORTHWESTWARD FOR THE MARIANA ISLANDS OVER
THE WEEKEND. THESE FEATURES WILL GENERATE SHOWERY CONDITIONS WITH
LOCALLY HEAVY DOWNPOURS BEGINNING AS EARLY AS FRIDAY EVENING THROUGH
MONDAY NIGHT. CURRENT MODEL OUTPUT SHOWS RAINFALL AMOUNTS OF UP TO
10 INCHES OVER THE MARIANAS BY MONDAY EVENING...WITH SUBSTANTIALLY
HIGHER AMOUNTS JUST WEST OF THE COASTAL WATERS AS THE DEVELOPING
CIRCULATION SLOWLY MOVES NORTHWARD. IF THE CIRCULATION MAKES A SLIGHT
SHIFT TO THE EAST...IT COULD BRING RAINFALL AMOUNTS IN EXCESS OF 20
INCHES TO THE ISLANDS.
THIS DEVELOPING SITUATION WILL CONTINUE TO BE MONITORED CLOSELY AND
FLOOD WATCHES AND ADVISORIES WILL BE ISSUED WHEN NECESSARY. HEAVY
DOWNPOURS COULD PRODUCE FLOODING IN URBAN AND LOW-LYING AREAS...AND
FLASH FLOODING NEAR RIVERS AND STREAMS.
NOW IS A GOOD TIME TO CLEAR DRAINAGE AREAS AND UN-BLOCK CLOGGED STORM
DRAINS IN YOUR AREA TO MINIMIZE THE CHANCE OF FLOODING. RESIDENTS
LIVING NEAR RIVERS AND STREAMS NEED TO REVIEW PLANS FOR PROTECTING
PROPERTIES.

Re: WPAC:INVEST 92W
Having doubts this will even be the dominant circulation. UKMET disses this and develops another stronger system right behind west of the Marianas. EURO the same but slams it on the Marianas.
GFS also has both systems but keeps this as the main system and bottoms it out at 898 mb!

Re: WPAC:INVEST 92W
Complicated scenario this evening as a disturbance with a weak,
elongated circulation center is not far southeast of Guam. Since it
is so near already, the wind threat is likely low. However, it could
easily dump a substantial amount of rain, and with antecedent
moisture already running high, there will not be much room for more.
It is against this backdrop that a clear plurality of the numerical
weather prediction models show amounts of 6 to 10 inches over the
next 4 days, with amounts as high as 20 inches possible if the GFS
pattern should happen to shift east a bit.
Took a while to figure out which model wind field looked the most
reasonble. The ECMWF-HiRes had some unfortunate convective feedback.
The GFS was ramping up the winds too quickly. Eventually went with
the NavGem, at least as a starting point. Capping the winds at 21
knots eased the tendency it showed of also spinning up the winds what
looked like a bit too fast.
