90E in the eastpac
      #65181 - Sun May 14 2006 03:44 PM

Invest just went up on the NRL web site.

This was from the last discussion (1605Z). They must have liked what they see now. The last quikscat I looked at some hours ago it did look more symmetric.

LOW NEAR 9N99W...

LARGE CONVECTIVE BLOW-UP BEGAN AROUND 00Z LAST NIGHT AND WAS FOCUSED MAINLY AROUND THE S/SE PERIPHERY OF THE CENTER OF CIRCULATION. THIS ACTIVITY CREATED A NEARLY CIRCULAR 180 NM WIDE EXPANDING CIRRUS SHIELD BUT MORE RECENTLY THE CONVECTION HAS BROKEN UP INTO SEVERAL CLUSTERS ALIGNED ALONG THE ITCZ AXIS AND S OF THE CENTER. A 1252Z QUIKSCAT PASS INDICATES THAT THE LOW-LEVEL CENTER IS STILL SOMEWHAT ELONGATED SINCE IT HAS NOT YET DETACHED FROM THE ITCZ...BUT IT IS BECOMING INCREASINGLY MORE CIRCULAR AND COMPACT. THE DEEP CONVECTION HAS NOT DIED OFF LIKE IT DID THIS TIME YESTERDAY SO IF THIS TREND CONTINUES THEN TROPICAL CYCLONE DEVELOPMENT WOULD BE MORE LIKELY IN THE NEXT FEW DAYS. SEE ITCZ FOR RELATED CONVECTION.

ITCZ CONVECTION REMAINS QUITE ACTIVE FROM 90W-105W ESPECIALLY IN THE VICINITY OF A 1007 MB LOW LOCATED NEAR 9N98W. SATELLITE IMAGERY INDICATES THAT CONVECTION NEAR THE LOW CENTER HAS BEEN STEADILY INCREASING OVER THE LAST 24 HOURS BUT REMAINS DISORGANIZED. AS SUCH...IMMEDIATE DEVELOPMENT IS NOT EXPECTED BUT SLOW STRENGTHENING OF THE LOW IS POSSIBLE AS IT MOVES WESTWARD AT 5-10 KT DURING THE NEXT DAY OR SO.

It looks like the following composite is possibly going to be phased out.

So here's another link for use as the low moves westward.

I thought it would be fun and interesting to post the first eastpac TWO, as it contains a list of names for the season and other information. At least I think it's the first one, because I didn't check earlier today.

One of my favorite names is on the list - Emilia. I thought it was funny that someone decided you might need help figuring out how to pronouce it! (my grandmother's name was Emilie - German for Emily -- but I've always liked the Spanish/Italian variant).
