A large area of disturbed weather is expected to become a tropical storm in the next few days.
Guam – The National Weather Service talks about another possible appearance of a tropical system in the Pacific.
In its Area Forecast Discussion from this morning, NWS writes, “Satellite imagery shows a large area of disturbed weather east of the date line with a broad center around 5N170W. Both the GFS and the ECMWF show a tropical cyclone developing out of this in the next few days…crossing the dateline late Sunday or Monday.”
GFS takes this area to become a tropical storm by early next week and brings the new system to pass near the Marianas on early August. But the Weather Service expects Marianas’ weather to be affected by this possible system as early as late next week.
Because the forecast of the disturbed area is far from the islands, certainty level in its forecast is extremely low; however, this is a possible scenario. Most recent typhoon Halola also started from the east side of the date line. Originally Halola was predicted to dissipate before coming any closer to Marianas, but as it turned out, the typhoon passed both date line and Marianas.
“Of course…uncertainty is high this far out…but this is likely the first indication from the models of an upcoming active period for monsoonal action and the development of one or more tropical cyclones,” NWS comments about this area of disturbed weather.
