I think Emilia is in the process of re-intensifying a bit today. Pretty good microwave presentation and the lack of banding features does indicate some potential for the system to become Annular under low shear and somewhat low SSTs over the next 24 hours. It does need to clear out that eye quite a bit more first though.

Same as yesterday. Northwestward but stays far away from MX.

:angry:

Looks pretty nice, actually. I'd be excited to get in a cyclone core with a MW presentation like that this year. It's not perfect, but it's totally decent.

Looks like Phil was right! Semi-annular looking right now (still has potential to go annular tonight), but is definitely unaffected by cooler SSTs.

ADT is actually the highest it's been so far, even stronger than Mon night.

Col pic, Turtle-- thanks for posting it!

Emilia is weakening this morning, while TD 6E has formed (from last night's cherry) and is forecast to strengthen into a 'cane. A trough will dig down and steer it more N eventually-- but it will weaken as it starts to recurve.

Blah.

Emilia is being darn persistant and is back up to a Cat 3 for the third time in its life. TD 6E has become Fabio! If it becomes a hurricane, it will be the 5th storm in a row in the EPac to do so. Needless to say, the EPac is on fire!

Yep. More and more, I'm thinking this season's salvation is going to be October in the EPAC. Just have that feeling. It's the vibe I'm getting.

Talk about quality over quantity the last 2 years.

Since the start of hurricane season 2011:

EPAC: 17/15/9 (assuming Fabio becomes a hurricane)

ATL: 23/8/4

So a whopping 88% of TSs in the EPAC have become hurricanes and 53% have become majors, while in the Atlantic only 35% of TSs have become hurricanes and only 17% have become majors!

Just curious, with the SSTs below normal around Hawai'i, does anybody have an anomaly chart handy for July 1992, the Iniki El Nino year? 1997 if its readily available.

TIA

I'll help you out again Ed! ;)

You can tell that the warm anomalies extending into Hawaii in 1992 really made the difference. Pacific SSTs in 1997 were overall warmer, but not in the favored storm track.

1992:

The over night Euro remains offshore of the Mexican Riviera with the next developing disturbance. The GFS suggests the same, but that model also suggests 2 additional storms developing in the longer range. It getting to be that time of year... ;)
