Typhoon Conson kills 18 in the Philippines; record SSTs continue in the Atlantic

By: Dr. Jeff Masters , 1:27 PM GMT on July 14, 2010

Tropical Storm Conson hit the Philippines' main island of Luzon yesterday as a strong tropical storm with 70 mph winds. Conson was briefly the season's first typhoon on Monday, when it intensified to an 80 mph Category 1 storm. Conson is being blamed for at least 18 deaths in the Philippines, with 57 other people missing. The storm caused an extended power outage to the entire island of Luzon. Conson is headed towards a second landfall later this week in China, but should not intensify into a typhoon again because of the presence of 20 - 30 knots of wind shear. Conson is only the second named storm in what has been an unusually quiet Northwest Pacific typhoon season. According to Digital Typhoon, an average season has six named storms by mid-July.

June SSTs in the tropical Atlantic set a new record
Sea Surface Temperatures (SSTs) in the Atlantic's Main Development Region for hurricanes had their warmest June on record, according to an analysis I did of historical SST data from the UK Hadley Center. SST data goes back to 1850, though there is much missing data before 1910 and during WWI and WWII. SSTs in the Main Development Region (10°N to 20°N and 20°W to 80°W) were 1.33°C above average during June, beating the previous record of 1.26°C set in June 2005. June 2010 is the fifth straight record warm month in the tropical Atlantic, and the third warmest anomaly measured for any month in history. The only warmer anomalies were 1.51°C and 1.46°C, set in May 2010 and April 2010, respectively. As I explained in detail in a post on record February SSTs in the Atlantic, the Arctic Oscillation (AO) and its close cousin, the North Atlantic Oscillation (NAO), are largely to blame for the record SSTs, though global warming and Atlantic Multidecadal Oscillation (AMO) also play a role. The magnitude of the anomaly has fallen over the past month, since trade winds over the tropical Atlantic have increased to slightly above-normal speeds. These higher trade wind speeds are due to the fact that the Bermuda-Azores High has had above-normal surface pressures over the past month. The Bermuda-Azores High and its associated trade winds are forecast to remain at above-average strength during the next two weeks, according to the latest runs of the GFS model. This means that Atlantic SST anomalies will continue to fall during the remainder of July. However, keep in mind that we are talking about anomalies--the ocean will continue to warm until its usual early September peak in temperature, and it is likely that we will have the warmest or second warmest SSTs on record over the tropical Atlantic during the peak part of hurricane season, mid-August through mid-October.

The tropics are quiet
There are no threat areas to discuss in the tropical Atlantic today, and none of the reliable computer models is calling for tropical cyclone development over the next seven days. The NOGAPS model is calling for a strong tropical disturbance to form off the Nicaragua coast this weekend. If this disturbance forms, it would move west-northwest and bring heavy rains to Nicaragua and Honduras early next week.

Next post
I'll have a new post on Thursday.

A met in Orlando that I live near told me yesterday that August thru October could one of the wettest in many years for C and S FL.



I don't know if I believe that, I thought this year would be real wet like last year, but sadly, ever since La Nina began to pop, things have really dried out around here.

Yeah we had that really wet pattern in late June into early this month, but other than that there has been nothing but clear skies and isolated storms. Lame and dry, just like June was.

dude we might just be headed back into another drought again in Florida :(


It still has never has been as wet in stormy as it used to be when I was real young. My dad would always tell me about when he grew up, year after year, you could count on a big thunderstorm every single afternoon almost, June through September.

Not anymore.... I wonder if Florida will be the newest subtropical desert in 50 years? We are getting a head start.


Cause my area averages 58 inches of rain a year, we used to get more then that pretty often during my early days. Now we are lucky to hit 40 these days it seems.

Thanks Chicklit for the reply.

Looking for something like this but without the current satellite images imposed.
Just a template to look at when I want to reference the location of specific coordinates of a wave.

Jeff just made a general comment about we could see a typhoon like storm and this Kid always has something to post that will oppose something even as general as Jeff posted. If he is gonna post and i do enjoy his humor and knowlegde on here as many but, many are tired of these kids post that challenge even general comments. Its one thing to oppose ones specific statement but, 2 or 3 on here challenge just the general and most general statements for no reason. Everyone have a great day!
So you mean minors on this blog in general?

Heck, after what we saw with Alex, it seems possible Jeff may be very well right. I hope he's not, no one needs a Tip like storm, but it seems the ingredients are largely there for something large and impressive in the coming months.

Good Morning all!

Anyone have a good graphic reference with coordinates grid, so when I read coordinates I can quickly reference where that is?

Hi JBird,
If you go to the NHC site (here) NHC there is an array of satellite photos and the weather discussion available.
To get Satellite you click on that (on the left screen) and then pick your region. The Java or Flash versions will give you grids of whatever region you're looking for.
A lot of folks use the GOES site, but I prefer this one because it's easy to use and you can also see the Tropical Weather Discussions and all of the warnings when there's an active system.
Hope this helps.

P.S. Here's the GOES site link: NOAA You may prefer to use this one because you can get grids on the stills. Just click on the icon of whatever area you're interested and choose from the menu below. You can get InfraRed, WaterVapor, etc.

Morning all, thought I'd share a line or 2 of this mornings NWS forecast discussion for my area of central Indiana.

.NEAR TERM /TODAY/...

HOT. TROPICAL. SULTRY. SWEATY. OVENLIKE. DID WE MENTION HOT?
THESE ARE ALL WORDS THAT COULD BE USED TO DESCRIBE THE WEATHER
TODAY IN CENTRAL INDIANA.


Heat indexes approaching 105 here, which may seem tame to some of you who live south, but for us, this is bout as bad as it gets. Personally, I can't wait till November!
Ok out to make a buck in this tropical tundra, have a nice day all.

Dr. M mentioned that area in his blog yesterday (see above)....Going inland into Honduras/Nicaragua; could also cross over to the E-Pac IMHO if the energy remains intact.
Steering over the area is very weak, so if anything develops there it will likely meander for several days before being picked up with a more WNW motion into Nicaragua/Honduras.

Got to go, later everyone!

I believe we will see our next invest in the SW Caribbean sometime in the next 48 hours. The upward motion of the MJO has begun to come into that region. There are also favorable upper level winds. Something else that we don't see with those flare-ups of convection down there is lower convergence, which this system indeed has. Steering is very weak over this area, but should become stronger and a bit more northerly with time.

Morning all. I like that new fimz model. easier to read than some are. Of course now that it doesn't show something coming to me helps with its popularity. Lol

This mornings CMC and GFS2 show upper TX cost hits 2 days apart. EURO in the neighborhood with blob-ish. Lol. I do think if the models hang on to this it will shift farther south. Kinda eerie they don't show anything crossing Florida on its way here. CMC ala Rita track. GFS2 out of Caribbean.

Hey I know this I believe I did go to school for this. Anyway everything else is in place for many monster storms this year (i.e Low Shear, high SST, above average moisture across the MDR region, and plenty of upeard motion coming. I could go on if you need me too.
That great if you went to school. But in your first comment you just said heat. You can have 100˚F SSTs but if upper level winds are unfavorable you aren't going to get much development of anything.

The wave approaching 60W looks a little suspect this morning. Not sure of the shear forecast down the road, rather high now though.

All of this heat content over the Atlantic is going to allow for some Typhon Tip type storms.
You need much more than piling of heat to allow for a cyclone of that intensity and size.

I suggest we watch the wave near 30%u02DAW-35%u02DAW and 17%u02DAN. 850mb vorticity has begun to consolidate, convection is also improving. SAL is diminishing, plus the wave has very nice cyclonic rotation in the lower levels.
