Kyle not strengthening

Tropical Storm Kyle continues to struggle with wind shear as it heads northwards towards Nova Scotia, Canada. Visible satellite loops show little change in the appearance of Kyle today, and wind shear of 15-20 knots is keeping any heavy thunderstorm activity from developing on Kyle's west side. Unless the shear relaxes, allowing Kyle's heavy thunderstorms to wrap all the way around the center, intensification into a hurricane will be difficult.The Hurricane Hunters measured top surface winds around 55 mph so far this afternoon, and Kyle's central pressure was a rather high 1003 mb at the 3:33 pm EDT center fix.


Figure 1. Current satellite image of Kyle.

The forecast
Wind shear is forecast to change little over the next 36 hours. This gives Kyle some time to intensify into a Category 1 hurricane, which the GFDL and HWRF models have been consistently predicting will happen. However, given the storm's current struggle to organize, I doubt Kyle will ever attain hurricane strength. By Saturday night, wind shear is forecast to increase to 25-35 knots, and the sea surface temperatures plunge from 26°C Saturday night to 13°C Sunday night. If, as I expect, Kyle is still a sheared 50-60 mph tropical storm at that point, it will probably decay to a 40 mph tropical storm by landfall. The latest strongest Kyle is likely to be at landfall is a 60 mph tropical storm, as predicted by the 12Z (8 am EDT) run of the GFDL model.

Storm surge should not be a major issue with Kyle. If it makes landfall in the Maine/New Brunswick region as a Category 1 hurricane, it would likely generate a storm surge in the 3-5 foot range, according to NOAA's SLOSH model. Given that the range between low tide and high tide is at least 12 feet in the region, Kyle would have to hit very close to high tide to cause any storm surge flooding. Kyle's likely impact as a tropical storm makes surge flooding problems improbable. Hurricane Edna of 1954, which hit just west of Eastport, Maine, as a Category 1 hurricane with 90 mph winds, generated a storm surge of just 3.4 feet at Eastport. If Kyle hits Nova Scotia as a Category 1 hurricane or tropical storm, a storm surge of 1-3 feet is likely. Hurricane Juan of 2003, which hit Halifax, Nova Scotia as a Category 2 hurricane with 100 mph winds, generated a storm surge of 4.9 feet in Halifax.

Kyle's cone of uncertainty covers the eastern coast of Maine and the western half of the coast of Nova Scotia. Recent model runs have trended to take Kyle a little more to the east, over Nova Scotia. This province will probably get Kyle's worst winds and rain, since wind shear is keeping Kyle's heaviest thunderstorms on the east side of the storm. My best guess is a landfall in western Nova Scotia as a tropical storm with 40-45 mph winds. According to the forecast wind radius images from NHC, tropical storm force winds of 39 mph and higher will miss Massachusetts, but may affect eastern Maine. Tropical storm force winds are also expected to miss Bermuda. (Use the wundermap with "wind radius" turned on to see the expected radius of tropical storm force winds).

Kyle's main threat is heavy rain. Kyle's rains will primarily affect Nova Scotia and New Brunswick at landfall on Monday morning. However, Kyle should pull copious amounts of tropical moisture and the remains of the unnamed storm that hit South Carolina last night northwards into Canada and northern New England. This will create potential serious flooding problems early next week in the region. NOAA is forecasting up to eight inches of rain could fall in New England over the next five days (Figure 2). The latest 12Z (8 am EDT) UKMET model run is forecasting that Kyle will stall after landfall. If this forecast verifies, there is the possibility that extremely heavy rains in excess of twelve inches will fall over northern New England, New Brunswick, and Nova Scotia next week. Near-record flooding with heavy damage would likely result. However, the other models do not go along with this scenario, and rain amounts in the 6-8 inch range are more likely for northern New England, New Brunswick, and Nova Scotia.

Middle Atlantic disturbance
An area of disturbed weather in the middle Atlantic, near 12N 42W, has changed little today. This morning's QuikSCAT pass showed an elongated surface circulation and top winds in the 20-30 mph range. Wind shear is 10-20 knots, but is expected to increase to 20-30 knots Saturday and increase further on Sunday, which should destroy the struggling circulation. NHC is giving this system a low (<20% chance) of developing into a tropical depression by Sunday.

Gulf of Mexico disturbance may threaten western Florida next week
An area of disturbed weather in the southern Gulf of Mexico, just west of Mexico's Yucatan Peninsula, has changed little today. Visible satellite images show a modest-sized area of heavy thunderstorms moving east-southeast, towards the Yucatan Peninsula. Wind shear is about 15 knots over the region, which is marginal for development. The system should move ashore over the Yucatan Peninsula by Saturday before development into a tropical depression can occur. NHC is giving this system a low (<20% chance) of developing into a tropical depression by Sunday. Early next week, we will have to watch the waters on either side of the Yucatan for possible development of this system. Some of the models are predicting that a tropical depression could form off the coast of the Yucatan Peninsula early next week, then move northeastwards to a landfall in western Florida as early as Wednesday.

The Hurricane Ike relief effort continues
Thanks to everyone who has contributed to the portlight.org charity! We raised enough money to send another truck with relief supplies to Winnie and Bridge City, Texas, where traditional relief efforts have fallen short. Wunderground member Presslord (AKA Paul Timmons, Jr.), who is coordinating this effort, has announced that if we raise an additional $10,000 mark, he will pose in a dress for our wunderphoto gallery. We're up to $2500 so far.


Figure 3. The town of Bridge City was inundated with a massive storm surge even though it was far displaced from Ike's landfall point. This speaks to just how massive Ike was. The people of Bridge City, Winnie, and other small towns in Ike's path will need help for a long time to come: www.portlight.org. Image credit: Storm Junkie.

Wow... seems that 12Z GFS wants to bring that Cape Verde storm closer to FL... but instead of getting it close... we're ending up with the same scenario we had with 94L and Kyle... in which this time it will be happening in FL and not up North.

I'm getting quite interested in what the 12Z ECMWF will show for the long range.

I can't believe how ridiculously overdone the QPF forecast is up there in New England, when we have big rain events in central Florida, they usually have like 2 to 4 inch QPF here, and they only issue flood watches every once in a great while, I mean like when we get a foot of rain or more.

And when they forecast 1 to 2 inches here, its always more like 2 to 4, with a few spots getting like 8. when they forecast 2 to 4 we usually get 6,8 or 10 inches...


I can bet you a lot of money that those 6 to 8 QPF forecasts are WAY overdone....


My point here is the NWS offices seem to severely differ across the country, they jump the gun up north too much, and down here they are too conservative... LOL


I agree with it if it is as you say. The terrain is different up there and there are places that "pool" with the more mountainous terrain. They should state on the high end for precip. In FL, the canal system, terrain and such allows for much more drainage.

Look up Wayne, NJ and flooding. Think above sea level New Orleans. They were, at one time, actually going to build a tunnel to drain out into the atlantic (can do that above sea level, wish they could do something similar for NO, but not possible).

And Wayne, NJ is 30 miles inland.

For JMA is the strongest (w pac storm) in 13 years, and there have been many typhoons considered cat 5 by JTWC in this period, hard to tell, i think they don't fly storms in that area and different centers have different opinions.

Every once in a while there comes along a storm that looks menacing and the region comes away relatively unscathed, Taiwan will not be as lucky with this one. I believe the damage from this one will shock alot of people. It's a large storm with a huge wind field. I can only imagine the storm surge from this one.

Ignorant, there's something up in the CB


Last night Dr. Lyons said that the area in the Bay of Campeche will move south and dissapate.

He is smart but one thing about him is that he is a major downcaster. He never sticks his neck out to forecast the development of a system.

The island of Taiwan lies some 120 kilometers off the southeastern coast of mainland China, across the Taiwan Strait, and has an area of 35,801 km2 (13,822.8 sq mi). The East China Sea lies to the north, the Philippine Sea to the east, the Luzon Strait directly to the south and the South China Sea to the southwest. The island is characterized by the contrast between the eastern two-thirds, consisting mostly of rugged mountains running in five ranges from the northern to the southern tip of the island, and the flat to gently rolling plains in the west that are also home to most of Taiwan's population. Taiwan's highest point is the Yu Shan at 3,952 meters, and there are five other peaks over 3,500 meters. This makes it the world's seventh-highest island. Taroko National Park, located on the mountainous eastern side of the island, has good examples of mountainous terrain, gorges and erosion caused by a swiftly flowing river.

The shape of the main island of Taiwan is similar to a sweet potato seen in a south-to-north direction, and therefore, Taiwanese people, especially the Min-nan division, often call themselves "children of the Sweet Potato."[22] There are also other interpretations of the island shape, one of which is a whale in the ocean (the Pacific Ocean) if viewed in a west-to-east direction, which is a common orientation in ancient maps, plotted either by Western explorers or the Qing Dynasty.

Background pressures in the WPAC are lower than in the Atlantic, so central pressures will be lower for any given strength storm. That being said, Jiangmi is quite an impressive storm, one of the strongest seen since Wilma and Monica in 2005.

hello all, looks like the system over the yucatan really wants to develop. convection is still firing up near belize. hey orca and storm what are your feelings on this one?


Well, the convection is in association with that trof...and is being enhanced by upper level divergence. Shear is suppsoed to drop in the western Caribbean over the next 48-72 hours, but is supposed to remain fairly high over the GOMEX. Could see some sort of not too organized system in a couple days...may head toward Central Fla. I think shear is just going to be too high for anything really organized. Could be a good rainmaker though. Have to see once it starts coming together.

hello all, looks like the system over the yucatan really wants to develop. convection is still firing up near belize. hey orca and storm what are your feelings on this one?


Well, the convection is in asscoiation with that trof...and is being enhanced by upper level divergence. Shear is suppsoed to drop in the western Caribbean over the next 48-72 hours, but is supposed to remain fairly high over the GOMEX. Could see some sort of not too organized system in a couple days...may head toward Central Fla. I thibk shear is just going to be too high for anything really organized. Could be a good rainmaker though. Have to see once it starts coming together.


thanks again storm for your valuable input!

Most of the time they mention cyclones in the western pacific, even weak ones, they might of just forgot.

How do they forget about a Cat 5?

I have no idea.
