Typhoon Chebi less destructive than feared
Posted by: Dr. Jeff Masters, 4:04 PM GMT on November 11, 2006 +1
Typhoon Chebi slammed into the main island of Luzon in the Philippines last night at 6pm EST as a Category 3 storm with top winds of 120 mph. There are no reports of deaths yet, and damage appears to be much less than occurred for Super Typhoon Cimaron, which made landfall October 29 as a Category 5 storm with maximum sustained winds of 160-180 mph. Cimaron killed at least 15, left 2500 homeless, and destroyed about 8% of the island's rice and corn crop. However, Chebi was a much weaker typhoon, and dumped far less rain on the Philippines since it moved across the islands relatively quickly. Rainfall estimates by NOAA (Figure 1) show maximum rain amounts from Chebi were in the 4-7 inch range, which should not cause the kind of widespread flash flooding and landslides that are the primary hazard of typhoons in the Philippines. Cimaron dumped about 50% more rain on the Philippines than Chebi did.

My next blog will be Monday, when I plan to discuss a new hurricane-like storm found on Saturn.

Ok, let's not all get carried away here. The models need to show some consistency, other than two model runs today. If they continue to show the same thing into tomorrow and beyond, then we really need to pay close attention.

I have seen too many runs showing a significant storm forming, only to find that the following mornings runs drop it. Let's see if the models still show this tomorrow.

Nash28 global models have been hinting on development since nov 10 with different scenarios playing out.But overall futher consistency with the models will be key.

Howdy do everyone. Everyone having a good day? Is that a ULL off the coast of Virginia/Maryland? Kinda reminds me of Thingamabobbercane.

Well guys, regardless of what actually comes of this system the models are predicting, I believe it is safe to say we will have an Invest at the very least sometime this week:-)

finally some action and the major models are agreeing of some development, i say we get a minimal hurricane to be optimistic.

107. nash28 10:27 PM GMT on November 12, 2006    
I wouldn't go that far just yet Drakoen. First, we need to monitor the shear levels in that area and see how it is behaving. Secondly, due to the synoptic pattern we have been embedded in for quite some time now, shear levels in the Gulf and Northern Carribbean have been very high, so any change there would be significant. I believe we will get a TD out of this, but beyond that??? Too early to tell. Let's see if the models continue to be in good agreement...

Just looked at the 18z GFS and it continues to be very persistent in developing a tropical system in the western caribbean.

I see that. This time, it takes the system over Hispanola and out to sea, once again sparing the U.S. from a hit.

Let's see if our luck will continue...

I expect track guidance disagreement on this one...

Hurricaneblast global models indicate that tropical cyclone development might occur in the western caribbean.Some models are more aggressive then others and tracks are also vary with each model.The key thing to look at here is the overall consistency in the models.

so this thing is suppose to go to south florida
126. nash28 11:58 PM GMT on November 12, 2006    
Miami---

Not gonna discuss any tracks of something that hasn't even formed yet. Not being combative, but we need to see if the models continue to be in good agreement of genesis and whether this thing actually forms.....

Side note-- I hope the models are wrong...

I dont think overall conditions will favor significant intensification of system like the likes of LENNY.

Here is a visible pic of lenny in 1999...

Are we going to have to put our storm shutters
up again in SW Florida ?

Absolutely Miami. We have been blessed this year. Thank God!!!! We don't need anything....

Let them all be fishy storms. Great for study and no one gets hurt.

I also live in southflorida and for now there is not much to worry about but with so much model aggrement in my opinion its worth keeping a close eye on the situation.

Could the low at 30N 50W & moving South in to a low shear environment pick up a gulp of warm air? "Thingamabobbercane" did it with 15-16C.

Final #s on Queenie (Typhoon Chebi), in the Philippines. 1 dead, 5 missing, 9 hurt & 8,580 displaced.

A drunken man was reported to have drowned in a swollen creek after he fell off a bamboo bridge in Casiguran town..

The Philippine Atmospheric Geophysical and Astronomical Service Administration said Chebi is expected to gain strength as it heads toward Vietnam.

The typhoon hit landfall Saturday packing maximum winds of 131 mph resulting to the injury of eight persons in Casiguran.

Reports also said that at least five fishermen were missing when their outrigger boats capsized near Sabang, Quezon.

SFL is a long ways off from worring about anything gitten 'em from the Caribbean. Now those in Jamaica & areas around there (CMC) might want to think about what you may need to get if we see more consistancy with the runs & something develops. Seems the models are torn on how much influence the front will have on the possible disterbance.

The gale is kickin some waves. That looks more like an erosion set up then a good surf set up.

Hi Skye, . Not raining now but overcast. The rain today was unusual in that it was very stormy in appearance, but the rain fell in isolated heavy showers islandwide. I only got 1.25 " but where I was today felt like about 3" in 30 mins. The wave does look to be less well defined than it did earlier, I agree...Cant see it holding out, but this has been the season for peculiar.
