Guam – The Joint Typhoon Warning Center [JTWC] has issued a Tropical Cyclone Formation Alert for a system that, as of  Wednesday afternoon, was located about 375 miles south-east of Guam. 


The Wednesday afternoon alert from the JTWC states that “the formation of a significant tropical cyclone is possible … within the next 12 to 24 hours”.

The system does not have a name or number yet. The JTWC says “available data does not justify issuance of numbered tropical cyclone warnings at this time.”

No watches or warnings are in effect.

However the National Weather Service [NWS] in Tiyan says models show the system passing directly over Guam, possibly by Monday.  Senior Forecaster Mike Middlebrooke says we are in for a wet and windy through the weekend. 

The NWS says the tropical disturbance is expected to gradually move westward through Thursday night, and  then stall south of the Marianas on Friday.
