The operational and parallel GFS runs are showing the same scenario of a recurve, so I guess both are fine...

12Z GFS brings it down to 983mb east of Mindanao, weakens slightly and hits Visayas as a typhoon beyond +180 hours...

Another interesting one is a tight low pressure 1005mb at 170E but very long range +340 hours...

Talk about inconsistency.

GFS showing a recurve brushing Northern Visayas and Luzon in the 00z, 12z runs

GFS shows a Mindanao landfall in the 06z, 18z runs.

But all runs agree that we will see tropical storm Mekkhala...

Sigh. Another Hagupit-esque disagreement when the ridge clearly is strong. :roll:

They don't sound enthusiastic towards the GFS as Euro has nothing.

NWS GUAM

ASCAT WIND ANALYSIS
INDICATES A SHARP TROUGHING PATTERN SOUTH OF KOSRAE AND POHNPEI...
AND A BAND OF TRADE-WIND CONVERGENCE WITH WIDELY SCATTERED SHOWERS
IS FOCUSED BETWEEN 3N AND 6N. THIS WHOLE PATTERN HAS BEEN DEVELOPING
VERY SLOWLY. GFS IN PARTICULAR INDICATES A CIRCULATION WILL DEVELOP
IN THE BASE OF THE TROUGH...AND MOVE TOWARD WEST-NORTHWEST IN THE
COMING DAYS

THE GFS40
HAS CONSISTENTLY TRIED TO SPIN UP A TROPICAL CYCLONE OVER THE NEXT
FEW DAYS AND MOVE IT JUST SOUTH OF GUAM BY THE END OF THE WEEK.
CHOSE TO FOLLOW PREVIOUS REASONING AS THIS SCENARIO DOES NOT LOOK
VERY LIKELY AT THIS TIME...THOUGH THE SITUATION WILL BE MONITORED
JUST IN CASE.
