Tropical Storm Chantal is speeding westwards at 26 mph towards a Tuesday encounter with the Lesser Antilles Islands. Satellite loops show that Chantal has plenty of spin, with several well-developed low-level spiral bands that have gradually increased their heavy thunderstorm activity this morning. However, Chantal is fighting dry air associated with the Saharan Air Layer (SAL). The heavy thunderstorm activity near Chantal's center is rather thin, and there are virtually no heavy thunderstorms on the storm's north side, where upper-level northwesterly winds are creating light to moderate wind shear of 5 - 15 knots, and driving dry air into the storm. This dry air is readily apparent on water vapor satellite loops. Ocean temperatures are fairly warm, though, at 27.5 - 28°C. There have not been any hurricane hunter missions into Chantal yet, but an Air Force hurricane hunter aircraft deployed to St. Croix on Sunday, and is scheduled to investigate Chantal on Monday afternoon.

Forecast for Chantal
The 8 am EDT Monday forecast from the SHIPS model predicts that Chantal will experience low to moderate shear through Tuesday afternoon as it heads west-northwest at 25 mph towards Hispaniola. With ocean temperatures expected to warm to 28°C during that time, Chantal has the potential to intensify to a 65 mph tropical storm before hitting Hispaniola. Working against intensification will be the fast forward speed of the storm--tropical storms moving faster than 20 mph in the deep tropics usually have trouble intensifying. In addition, the Eastern Caribbean is an area where the trade winds accelerate, helping drive sinking air that discourages tropical storm intensification. Dry air will also slow down the intensification process, and I don't see Chantal making it to hurricane strength before interacting with the mountains of Hispaniola and/or Cuba on Tuesday night and Wednesday. This interaction may be able to destroy the storm, since wind shear is also expected to rise to the high range, 20 - 30 knots, Tuesday night through Thursday. Chantal has the potential to cause big problems for Haiti, which is highly vulnerable to flash flooding due to the lack of vegetation on the deforested mountains. However, there is a lot of dry air to the west of Chantal, which may act to keep rainfall totals in Haiti down to a manageable 2 - 4". Over 300,000 people are still homeless and living in makeshift tent camps in Haiti, three years after the great 2010 earthquake.

Once Chantal crosses Hispaniola and enters the Bahamas late this week, the trough of low pressure pulling the storm to the northwest is expected to lift out. It is unclear at this point whether or not this trough will be strong enough to pull Chantal out to sea, or whether the storm might be forced back to the northwest into the U.S. East Coast by high pressure building in.


Figure 3. There have been only thirteen tropical depressions or tropical storms that have formed July 15 or earlier that have passed through the Lesser Antilles since 1851, an average of one such tropical cyclone every thirteen years. Note that two of these storms, Dennis and Emily, occurred during the notorious Hurricane Season of 2005. There were five other pre-July 16 storms that formed east of the Lesser Antilles Islands, but did not pass through the islands (Bertha of 2009, Barry of 1989, and unnamed tropical depressions in 1967, 1978, and 2001.)

Chantal: an uncommon early-season Cape Verde-type tropical storm
Formation of a tropical storm east of the Lesser Antilles Islands in early July from an African tropical wave is an uncommon occurrence. Since Atlantic hurricane records began in 1851, there have been only thirteen tropical depressions or tropical storms that have formed July 15 or earlier that have passed through the Lesser Antilles, an average of one early-season tropical cyclone every thirteen years. Note that two of these storms, Dennis and Emily, occurred during the notorious Hurricane Season of 2005. There were five other pre-July 16 storms that formed east of the Lesser Antilles Islands, but did not pass through the islands (Bertha of 2009, Barry of 1989, and tropical depressions in 1967, 1978, and 2001 that did not become named storms.)

Chantal: a likely harbinger of an active Atlantic hurricane season
Chantal's formation on July 8 is an usually early date for formation of the season's third storm, which usually occurs on August 13. A large number of early-season named storms is not necessarily a harbinger of an active season, unless one or more of these storms form in the deep tropics, south of 23.5°N. According to Phil Klotzbach and Bill Gray, leaders of Colorado State's seasonal hurricane forecasting team,

"Most years do not have named storm formations in June and July in the tropical Atlantic (south of 23.5°N); however, if tropical formations do occur, it indicates that a very active hurricane season is likely. For example, the seven years with the most named storm days in the deep tropics in June and July (since 1949) are 1966, 1969, 1995, 1996, 1998, 2005, and 2008. All seven of these seasons were very active. When storms form in the deep tropics in the early part of the hurricane season, it indicates that conditions are already very favorable for TC development. In general, the start of the hurricane season is restricted by thermodynamics (warm SSTs, unstable lapse rates), and therefore deep tropical activity early in the hurricane season implies that the thermodynamics are already quite favorable for tropical cyclone (TC) development."

Two of this season's three storms have formed in the deep tropics--Tropical Storm Barry, which formed in the Gulf of Mexico's Bay of Campeche at a latitude of 19.6°N, and now Tropical Storm Chantal, which formed at a latitude of 9.8°N. With recent runs of the GFS model predicting formation of yet another tropical storm southwest of the Cape Verde Islands early next week, it appears that the Atlantic is primed for an active hurricane season in 2013.

Lol. Post 746 was definitely a joke, people. It was said as a joke due to the constant comparisons to past storms here.

Just finished with Forecast #2 for Chantal. Will post this in comment section of my recent blog as well. My gut is telling me Chantal might have a 50/50 shot at hurricane status now so I went ahead and forecasted 75 mph. I might need to adjust my forecast again tonight when I get home from work for sharp left turn at end of Day 4 or 5.

Your projected path is very similar to this in terms of track and not strength.

Leftward turn becoming a little more pronounced at the end of the forecast period on the 18z suite.



This could be more fun to watch than earlier thought. Thank God it won't be very strong. But still, could see lots of rain, squally weather. Could be a challenge to the emergency management community.

If that track occurs in the 12z GFS, I don't like an ULL backing away from it to the west like the GFS 500mb maps show. It also shows another ULL to the east of the Bahamas. Great ventilation setup in the Gulf.


Nope don't like it one bit, of course we're getting into 120-144 hrs range and beyond with that... already seen several changes in the current ULL's forecast evolution of strength, timing, location over just the past 2-3 days analysis, and the impact that's had on Chantal's outlook for this week ahead, so... We'll watch!

Chantal definitely has room to make some northward wobbles relative to the forecast track. If you look at the bigger picture, Chantal's circulation is still embedded in a larger wave "pocket," for which I have highlighted the inverted-V signature below. Chantal's center is locked to the western edge of the wave structure, positioned well to the south of the northern peak of the wave, and this setup means that Chantal has some wiggle room to make NW wobbles despite the predominantly westerly or WNW trade wind flow, as long as her center is south of the peak of the wave. If you are wondering how Cape Verde storms can move north in a westerly trade wind flow, this is how.



Great to have your insight again this year, Levi....

The NHC doesn't update the cone during intermediate advisories. Only full packages.


True enough I forgot that. The image was "new" but its a re upload of the same track. Thought it had been moved already. Nonetheless it will probably be moved later on tonight given the 18z suite. Its possible they wait until after we have recon data to put in but we will see.


My apologies.


Also on that note I am very curious as to what recon data will do for our suite. I want to see if that left turn becomes more pronounced or goes away.

If you look closely at the ensembles one of them shows a track almost identical to Katrina.

I am going to repost this for emphasis folks, because its very significant. GFS had this nailed down in two earlier runs, or suggested at it, and now we are seeing the suite start to shift.

And remember its only day one of this storm!. This is going to be a WILD ride. I am really concerned however, about what this does if it re-emerges into the GOM in any form. There is pure rocket fuel, 2005 style, out there right now.

A slight westward cone shift with the 2 pm update is noted:



NHC dont change their track during the intermediate advisory but the new 18z models have it curl back west into Central/South Florida. In anycase the cone will at least hug Florida's east coast.

Chantal looks poised for a round of strengthening soon. Each new frame shows thicker clouds developing on the northern half with even some new thunderstorms firing there. Recon could actually be getting there right when a storm is strengthening for once.





That's a first for them this year. ;) They've had bad luck with getting there in time.

Stronger Chantel gets early on..the more NW she will go. Western PR will probably get TS force winds, maybe even hurricane force if Chantel continues to organize tonight into Tuesday. Right now best guess is for Chantel to pass near Dominica on Tuesday and eastern Dom Rep Weds even and night. I expect Chantel to be around 60mph at least by 11am Tuesday if not stronger

Chantal seems to have gained more latitude at this point than forecast. It's have to move in a much more westerly direction to match up to the forecast points.

It could just relocate into the center of the convection, though.
