Hopefully this trend will continue until landfall. :) Land interaction appears to be taking the toll on the storm. Though this one is still barely on water, hours before it hits the land. Good that you are keeping an eye on this.

Banding is quite good though...
Land interaction may have affected convection but overall the structure has improved.

Notice the northern quadrant has more convection that what it had 12 hours ago, as wind shear has relaxed.

I expect this storm to intensify a little more before landfall as Lamon Bay is a hot warm fuzzy place for storms coming this way.

Actually starting to look good, wouldn'rt be the least bit surprised if its 40-45kts, I think the JWTC are somewhat too low at the moment given the ever improving microwave imagery.

I've got a feeling a proto eyewall is trying to develop looking at that microwave, looks like you'll have a bursting storm into landfalol, and they nearly always hold up well overland...

JTWC might as well not bother warning on this storm - forecasts lack any consistency and totally behind the curve so to speak. One reason I rant about this is because vast majority of the media as well as websites such as Wunderground and Tropical Storm Risk mirror their data.

Looks like Nockten is really ramping up and to my eye that does looks like some kind of proto-eyewall trying to form. Great to see PAGASA really engaging this one in a positive way.

Stay safe all our friends in Philippines, storms like this have a record of being quite deadly!
