I find that hard to believe! I have seen you repeat what someone has said from their previous blogs, practically verbatim. Come on Atmo, don't play coy. That is why I choose my words carefully with you. LOLOL or the Chinese version: #
Well we have had a storm form in May for the last 3 years in a row, and with the very favorable atmospheric conditions forecast to set up over the SW Atlantic (shear is already below normal), we could have a shot at another one this year.
That said, I want to see how western Caribbean and gulf SSTs look by early May. If they don't warm up as fast as we think from their currently frigid temps, then that could hamper early activity, as those are the areas where most early-season named storms form. Keep in mind that despite the record warm waters in the eastern Atlantic, it is unlikely that we will see anything form way out there during May or June.
Overall right now I think there is fairly high potential for a named storm in May or June, but we will know more after monitoring conditions through early May.
OK, xcool, we give up! Does that image have something to do with El Niño?
I can't tell if you're being funny or not lol.
Yes I was wrong on Ului. She was not expected to move as slowly as she did, thus spending nearly twice as much time over self-upwelled water than was expected by the models. This caused her core to collapse 6 hours before her convection could re-fire, decoupling her from the upper high and forcing her to start from scratch. This task is much harder than what she would have had to do if she had maintained her core, so she will not be able to strengthen to Cat 2 like I thought.
I did make that forecast 5 days before landfall you know :P I try to stick to my prediction unless I see strong evidence otherwise, which I saw after her core collapsed. I did not change it many times though...I changed the landfall location once and the intensity once during a 5 day period lol.
Im grey with some white so I agree,but Im Irish too so I have a green eyed redhead thang..But the Helmet covers it all well.
Also of note is there is a storm trying to get going in the WPAC. Looks promising IMO, almost destined to be a fish too.
This also ties in with the thing about lower shear than normal in the SW atlantic. I always remember the thing joe bastardi said when I watched him, that the pattern in the WPAC is almost always comparable to the WATL.
For a week of good living...Aimee Mann.

Would you mind if I used the SST anomalie animation you made in comment 237 to use in my Spring forecast blog entry?
I will be sure to credit you for the loop.
What does it mean. El Niño is weakening already?
Sure go right ahead.
I'm not sure what to make of his loop because it's not in the form of anomalies lol. Buoys in the area showed El Nino rebound with warming SSTs during late February and early March, but some of the stations appear to be coming down off their peak now.

1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 4.4N
148.4E, IS NOW LOCATED NEAR 3.0N 155.1E, APPROXIMATELY 320 NM
SOUTHEAST OF CHUUK. ANIMATED MULTISPECTRAL SATELLITE IMAGERY SHOWS
CURVED BANDING AROUND A DEVELOPING LOW LEVEL CIRCULATION CENTER
(LLCC). UPPER LEVEL ANALYSIS INDICATES THE SYSTEM IS LOCATED BENEATH
DIFFLUENCE ALOFT AND IN AN AREA OF LOW VERTICAL WIND SHEAR. AN
OBSERVATION IN THE VICINITY IS REPORTING HIGH SEA SURFACE
TEMPERATURES (SST) OF 29 DEGREES CELSIUS, FAVORABLE FOR DEVELOPMENT.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. DUE TO
UPPER LEVEL DIFFLUENCE AND HIGH SST, THE POTENTIAL FOR THE
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24
HOURS IS UPGRADED TO FAIR.
(2) NO OTHER SUSPECT AREAS.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 190000Z, TROPICAL CYCLONE 20P (ULUI) WAS LOCATED NEAR
16.5S 156.7E, APPROXIMATELY 630 NM EAST OF CAIRNS, AUSTRALIA, AND
HAD TRACKED SOUTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS.
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 65 KNOTS GUSTING
TO 80 KNOTS. SEE REF A (WTPS31 PGTW 190300) FOR FURTHER DETAILS.
(2) NO OTHER TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY: NONE.//
Are we getting philosophical?
Thanks!
Yeah, like some people, they run hot and cold. LOL How you doing Chicklit?
Just wanted to lend my input on the upcoming hurricane season. Right now, all the signs point towards a very active hurricane season. Given the weakening El Nino going towards a neutral ENSO by hurricane season, record SSTs for this time of year, and increased precipitation across the Sahel, things could be fittin to kick off early in the season. But all this means little right now as we have yet to see what general steering patterns will evolve for the upcoming season. Thats the most important factor that will determine the impact this upcoming season will have. All I can say right now to everyone is quoting the master Max Mayfield, "Prepare for the worst and hope for the best."
Grateful it's warmer today. Thought the last cold front was the last, now wondering if we're due one more next week.
that is really neat!

By our correspondent
Karachi
The city braved the hottest day of March on Friday when the mercury level soared to 42.2 degrees Celsius, breaking all previous records for the highest temperature in March, Pakistan Meteorological Department officials said.
On Thursday, March 18, the city wilted with 41 degrees centigrade as the maximum temperature, which broke the previous 12 year record. However, yesterday, the record was broken once again as the temperature rose to 42.2 degrees Celsius, Chief Meteorologist in Karachi Muhammad Riaz told The News.
Riaz said that the absence of rains along with dry winds from the north easterly direction were the cause of the present warm weather in the city.
“This phenomenon (of warm weather) is expected to continue in the coming months of April, May and June until the monsoon season starts. The temperatures can go up to 44 degrees Celsius in April and further rise to 46 degrees Celsius in May,” he elaborated.
“However, there is a possibility that when temperature increase so much, the atmospheric pressure over Sindh would become low and this would ultimately lead to the start of sea breeze and decrease the temperature in Karachi,” he maintained.
He said that the El Nino phenomenon has reverse effect on Pakistan and during this phenomenon, lesser rains occur in the country.
Sure looks likes there may be one more on the way.
Then after that has to be the last time.
My blog is still streched. Did they change something?
No, I think Geoffrey has become "educated" and joined the Firefox and Chrome club...lol :)
Hey, Chicklit, anything is possible. Look at this:
The Great Blizzard of 1888 or Great Blizzard of '88 (March 11 – March 14, 1888) was one of the most severe blizzards in United States' recorded history. Snowfalls of 40-50 inches (102-127 cm) fell in parts of New Jersey, New York, Massachusetts and Connecticut, and sustained winds of over 45 miles per hour (72 km/h) produced snowdrifts in excess of 50 feet (15.2 m). Railroads were shut down and people were confined to their houses for up to a week.[1]
You know Levi, some of us can't change to Firefox or the others because of certain systems we have or restrictions on our PC's.
I hope you haven't been being serious Geoffrey....I've only been joking.
Thanks for the Graphs Levi. Atmo and I check the world buoys quite frequently. There has been quite a fluctuation in them lately. Don't know what that means.
