Future Walaka. Been a good minute since we have spawned a CPAC brewed system.

Yeah, back when I was first looking up stuff about Iniki and the season surrounding it I was like "Wait, they already had the I storm!" Didn't know they pulled from a different list that doesn't reset alphabetically every year for storms that are named west of 140.

Some of the intensity guidance is very bullish on this. I'm pretty intrigued. CPac storms are neat.

Not a meteorologist, in fact more of an idiot than anything. You should probably check with the NHC or a local NWS office for official information.

Very high ceiling if this stays below 20N

Yeah if it stays relatively low the potential for this is through the roof. It will pass through the holy grail of warm SSTs globally southwest of Hawaii. This to me has Cat 5 long tracker written all over it.

90%/100%

Showers and thunderstorms associated with an area of low pressure
located around 650 miles south of Honolulu, Hawaii have become
better organized early this morning. Environmental conditions are
forecast to remain conducive for development over the next several
days, and the low will likely become a tropical depression
later today or tonight while it moves westward at around 15 mph
across the central Pacific, well to the south of Hawaii.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 5 days...high...near 100 percent

I wouldn't mind a long-tracking, high-intensity basin-crosser to track. Ioke was one of my favorite storms to track back in the day.

Seems surprisingly bullish from the CPHC, though probably a very good call based on guidance. Always really interesting to have a Hawaiian-named major.

This is the system I'm most interested in globally. Looks really good on satellite and the ceiling is high. Might be some impressive rapid intensification. I also really like the name. Walaka. Wish they would send some planes to Hawaii and fly some research missions, could get some really good data.

Would agree of all the active systems globally, Walaka has some of the most pristine, untouched warm, deep waters. Others have to deal with latitude, up-welling from previous systems etc. If core can really take it to town my guess for this system is 150kts at peak.
