Likely showers with up to 60% chance of rain are expected in Marianas for next couple of days.
Guam – The National Weather Service expects wet weather over the Mariana Islands for early this week; this is due to a circulation northeast of Chuuk (at about 8,600 miles away from Guam) moving northward along with monsoon trough that stretches to Super Typhoon Champi.
In its Area Forecast Discussion from this morning, NWS writes, “This circulation is predicted to move northward. As it moves northward convergence south of the monsoon trough will spread across the Marianas.” As a result of the circulation–or Invest Area 93W– and monsoon trough moving, Marianas may see scattered showers by tonight. According to 7-Day Guam/Saipan Forecast Table from NWS, Marianas is said to expect up to 60% chance of rain around Tuesday afternoon and through Wednesday.
NWS comments “High pressure ridging in under the monsoon trough will allow the scattered showers to taper off by Thursday night,” regarding when the weather could improve.
