PRECAUTIONARY/PREPAREDNESS ACTIONS...

Thunderstorms east and south of Jebi continue to pose a risk for
lightning, gusty winds, and locally heavy rainfall today. The
potential for lightning strikes and gusty winds blowing loose
objects can make being outside hazardous at times, and heavy rain can
make travel difficult. Continue to monitor local conditions and the
sky before traveling away from shelter. When thunder roars, get
indoors, And when you see a flash, dash inside.

...Winds...
South to southeast winds of 20 to 30 mph this morning should decrease
to 15 to 20 mph later this afternoon or tonight, with winds becoming
more southeast as Jebi continues to move away. Gusts up to 40 mph are
still possible, especially if a thunderstorm moves over an island. By
Monday, a more typical trade-wind flow will extend across all of the
Marianas.

...Coastal inundation and surf information...
With winds decreasing surf will also to start to decrease below 9
feet later today or tonight.

...Inland Flooding...
At 4AM this morning, satellite derived Ensemble Tropical Rainfall
Potential (eTRaP) showed the potential for 1 to 3 inches of
additional rain within the heavy showers and thunderstorms of Jebi,
with locally higher amounts possible. This however does not account
for any development of additional showers or thunderstorms east or
south of Jebi. Exact amounts will vary depending how quickly showers
and thunderstorms pass over the islands, and how may rounds of
showers and thunderstorms each island experiences. Rainfall amounts
may be lower or higher than the potentials estimated by eTRaP,
however, high rain rates over a short period of time will lead to
flooding in low-lying areas and make travel difficult if not
dangerous, especially in areas with poor road or foot path access or
maintenance.
