Description:
ESFPPG
An active trough to the north is projected to drift southward and
move over the territory by midweek. This trough should remain
strong and active while over the territory, and may even intensify
with embedded low pressure centers. Widespread showers may be
heavy and persistent at times with the possibility of
thunderstorms. Widespread flash flooding may occur from this
rainfall, and landslides will be possible along steep mountainous
terrain. Impacts could begin as early as Wednesday and are
expected to persist through the weekend. While there is still
uncertainty in the exact magnitude and duration of rainfall, plan
now for wet conditions that could start as early as Wednesday and
persist through at least Sunday.
