- A broad tropical disturbance will interact with a shear line,
impacting the Marianas late this week, through the weekend,
and into next weekend. Several rounds of heavy to very heavy
rainfall will be possible during this time frame. This could
lead to 5 to 10 inches of rain across the Marianas with
locally heavy amounts. Due to the wet antecedents from early
this week, the conditions for flash flooding could be met at
a lower threshold.
