WPAC: NORU - Low
A new invest has been designated in the subtropical waters of the WPac. I have to say, I wasn't expecting this tag.

95W INVEST 170718 0000 25.5N 164.5E WPAC 15 NA

Re: WPAC: Invest 95W
"weak' LLC with some north-northwesterly shear forcing the convection onto the south and southeastern quad. Worthy within my opinion of being an invest.
If the convection can build more over the LLC this could be something.

Re: WPAC: Invest 95W
AN AREA OF CONVECTION (INVEST 95W) HAS PERSISTED NEAR
27.4N 161.8E, APPROXIMATELY 550 NM NORTH-NORTHWEST OF WAKE ISLAND.
MULTISPECTRAL SATELLITE IMAGERY SHOWS PARTIALLY ORGANIZED DEEP
CONVECTION WITH LOW LEVEL CLOUDS BEGINNING TO WRAP INTO A
DEVELOPING LLCC. WEAK OUTFLOW IS OFFSET BY LOW (5-10KT) VERTICAL
WIND SHEAR. THERE IS SLIGHT IMPROVEMENT IN THE SYMMETRY AND
STRENGTH OF THE 850MB VORTICITY SIGNATURE. SST IS FAVORABLE AT 29C
AND THE SYSTEM IS STILL BEING ASSESSED AS TROPICAL. MAXIMUM
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM
SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1013 MB. THE POTENTIAL
FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE
NEXT 24 HOURS IS UPGRADED TO LOW.

Re: WPAC: Tropical Depression 95W
Can't believe i'm saying this but it does look alot better than Don. Bandings and a huge convective blowup near the estimated center. Don was upgraded at 1.0 dvorak. Recon only way to confirm anyone?

Re: WPAC: Tropical Depression 95W
Honestly, a good case could be made that it is already a depression or if we're going to take the standards of cindy & Don maybe a tropical storm.

Re: WPAC: Tropical Depression 95W
Seems like the basins outside the Atlantic has to be really organize to be a TC especially the EPAC and WPAC using the satellite estimation. Pathetic.
Just how many would we have found here with recon even though short lived like Don?

Re: WPAC: Tropical Depression 95W
Latest ASCAT shows no closed circulation and maximum winds of around 25 knots under the deep convection. I personally won't upgrade it or classify it as a TC attm.

Quite irritating with JMA. Like a Pro-met on here says, it's like JMA upgrades every LPA to a depression no matter how they look and now a TS? Wish they would give an explanation. It's like NHC upgrading something with just the forecast advisory...
