NWS says models show this system becoming a tropical clone over the weekend or early next week.
Guam – The National Weather Service is keeping an eye on another low pressure system in the Western Pacific. As of this afternoon, the disturbance labeled as Invest Area 99W was reported to be located to the north of the Marshall Islands, at about 11N170E. That is about 1,760 miles from Guam and 1,697 miles from Saipan.
As the circulation is still in its developing stage, not much details were disclosed about 99W; however, NWS writes in its Area Forecast Discussion from this afternoon, “Models tend to slowly develop the system into a tropical cyclone and move the feature generally west over the weekend then to the northwest early next week. Nonetheless…this situation will have to be watched very closely with models showing run-run-consistency in timing and placement of the system.”
As for the short term forecast, the Marianas is expected to have quiet weather unless monsoon trough associated with the newly developing system gets activated over the forecast zone.
