Flooding possible in low-lying areas

Posted on Dec 01 2020
The National Weather Service in Tiyan, Guam, is predicting that locally heavy rainfall is possible late Wednesday and Thursday,
As per NWS information compiled at the CNMI Emergency Operations Center State Warning Point, a broad surface trough is expected to develop near Yap and Palau on Wednesday that curves east-northeastward to the Marianas. A trade wind disturbance, currently well east of the Marianas near 168E, will impinge on this trough. Global models suggest a weak circulation may manifest itself just south or southwest of Guam early Thursday. The end result is enhanced low-level convergence and plenty of moisture to squeeze out showers. This scenario may lead to heavy showers at times and showers that train over a certain area. Rainfall amounts of 2 to 4 inches are possible during this time, though local amounts could be substantially higher.
Localized flooding will be possible in low-lying and poor drainage areas while flash flooding will be possible in areas of the heaviest rainfall, especially near steep terrain. Already saturated soils will add to the flooding potential. This developing situation will continue to be monitored closely and a flash flood watch may be issued, if conditions warrant.
The public is being advised that localized flooding will be possible in low-lying and poor drainage areas. Check storm drains in your area to make sure they are not clogged. If planning anything outdoors this week, have a backup plan in place. (PR)
