Nate makes landfall; Maria organizing, but pulling away from the islands
Posted by: Dr. Jeff Masters, 4:15 PM GMT on September 11, 2011 +20
Tropical Storm Nate made landfall at 11 am EDT this morning just north of Barra de Nautla in the Mexican state of Veracruz, as a tropical storm with 45 mph winds. Satellite loops show that there is very little heavy thunderstorm activity associated with Nate, and the storm should not cause significant flooding or damage as it pushes inland and dissipates later today.


Figure 1. Visible satellite image of Nate as it made landfall in the Veracruz state of Mexico near 11 am EDT Sunday, September 11, 2011.

Tropical Storm Maria
Tropical Storm Maria has managed to organize in the face of the persistent moderate wind shear that has affected it, and now looks a little more like a tropical storm should. Though the center of circulation lies partially exposed to view, satellite imagery shows a large area of heavy thunderstorms lies to the northeast of Maria's center. These rains and the storm's strongest winds lie well away from the Lesser Antilles Islands, though one spiral band is bringing heavy rains to the islands, as seen on Martinique radar. A wind gust of 40 mph was reported on St. Martin at 11 am EDT, and one of 36 mph affected St. Kitts and Nevis at 9 am EDT during a rain squall. The trough of low pressure that is bringing hostile wind shear to Maria is predicted to slowly weaken over the next few days, which should allow the storm to grow to hurricane strength by Tuesday. On Wednesday, Maria will be making its closest approach to Bermuda, and the island could see sustained winds in the 20 - 40 mph range. Most of the models show that Maria will brush or strike Newfoundland, Canada on Friday or Saturday, and residents there should anticipate the possibility of tropical storm conditions late this week.

Extratropical Storm Katia
Hurricane Katia brushed by Newfoundland, Canada yesterday morning, and is now racing east-northeast at 50 - 60 mph across the open Atlantic. On Monday, the storm will pass very close to the northern British Isles, bringing winds of 50 - 60 mph to the offshore waters of Northern Ireland and Western Scotland. Ex-Katia will bring 2 - 4 inches of rain to the coast, and its strong winds will likely cause significant tree damage and power failures.


Figure 3. The center of Extratropical Storm Katia is predicted to pass just north of the British Isles on Monday, bringing a large area 45 - 50 knots (52 - 58 mph, red colors) to the coast. This wind forecast is from the 00Z (8 pm EDT) run of the GFS model made last night. To convert from knots to mph, multiply by 1.15.

Elsewhere in the tropics
Most of the models predict the development of a tropical depression or strong tropical disturbance 5 - 6 days from now off the coast of Africa.

I'll have an update Monday morning. Peace to all this September 11!

Interesting question. Wonder where to find the answer....


The WMO sets the rules for naming storms, in their document setting out names for the Atlantic/Caribbean it has the following statement:

The Greek alphabet (Alpha, Beta, etc.) will be used to name additional cyclones.

http://www.wmo.int/pages/prog/www/tcp/documents/F actShtTCNames1July05.pdf


This would lead me to believe that they would start again with Alpha, which also seems to me to be the logical way to proceed.

This thing about the Horn of Africa Drought reminds me of some conversations we had a few seasons ago about the teleconnections and the role of ENSO/El Nino in Indian Ocean cyclones. I suppose I should not be surprised to see that la Nina has contributed to drought conditions in more than just the southern US....


Anything that affects such large bodies of water like La Nina and El Nino has the ability to affect weather patterns globally. I suspect if we start looking at some really awful events such as droughts, or flooding conditions in one place, we might find them in another on a regular basis.

Jeez, seriously? WU admins aren't though enough with trolls and go overboard with good bloggers that strike a joke or two?

At this rate this blog will loose all it's good members and end up in the trash. Sorry for being so black and white about it, but it's the truth.

No wonder yesterday Maria exploded and the blog was dead, I remember back in 07, used to blog till very late/ early in the morning and there were people at that hour. Now there aren't any.

Well, enough of that. Maria's intense convection started weakening.

Well, I should change the wording a little...Ophelia OVER the weekend.

From an African wave the models are hinting at developing in the Eastern Atlantic in 5-7 days.

That's true.
But the advertisers pay for the traffic.

Everything in moderation(sic), some break in the tension, it helps to create a larger more attractive and cohesive community for advertisers. imo
