...TROPICAL DISTURBANCE NOW THE SUBJECT OF A TROPICAL CYCLONE
FORMATION ALERT...
THE JOINT TYPHOON WARNING CENTER HAS ISSUED A TROPICAL CYCLONE
FORMATION ALERT FOR THE TROPICAL DISTURBANCE CENTERED NEAR 5.9N
141.5E.
THE DISTURBANCE IS...
ABOUT 304 MILES SSE OF ULITHI IN WESTERN YAP STATE
ABOUT 320 MILES SOUTH ESE OF NGULU
ABOUT 340 MILES SOUTHEAST OF YAP
ABOUT 443 MILES SSE OF FAIS
ABOUT 494 MILES EAST SOUTHEAST OF KOROR
A developing circulation, also known as JTWC Invest Area 94W, is
centered near 6N142E. This system is still expected to undergo slow
development over the next several days as it drifts toward the west-
northwest. Heavy showers are currently over portions of Yap State,
including Yap proper, and are expected to continue for the next
several days. There remains high uncertainty on exactly what this
system will do over the next week, however, it does appear likely
that Yap and Koror will see periods of heavy rainfall through the
end of the week.
Occasional heavy showers are already affecting Yap, including Yap
proper, Ulithi, Ngulu and Sorol. As the system continues west-
northwestward, heavy showers are expected to spread into Palau
Tuesday or Tuesday night. Latest guidance now indicates most of the
showers will remain north of Sonsoral, with Koror and Kayangel
seeing the greatest potential. Regardless, significant rainfall and
gusty winds are possible for all of these locations through the
week. Latest model guidance indicates that there could be sufficient
rainfall to create a high risk of mudslides over the next few days
as well. WFO Guam will continue to monitor this disturbance and
issue updated information as needed.
Residents across the Republic of Palau and Yap State need to monitor
this developing situation closely and stay up to date with the latest
information from your local weather service offices. Listen to
instructions from your emergency management officials. The latest
local forecast can be found under WMO Header FZPQ52 PGUM and also on
the WFO Guam website:
