TD 16 organizing; Mexican landslide kills hundreds; hottest day ever in Los Angeles

The large area of low pressure centered just south of Cuba's Isle of Youth has developed enough of a well-defined circulation to be classified as Tropical Depression Sixteen, and is likely to become Tropical Storm Nicole by Wednesday. The depression has a very broad center, with little heavy thunderstorm activity near the center, and is this very dissimilar to the usual types of tropical depressions we see in the Atlantic. The large size, broad center, and lack of heavy thunderstorm activity near the center of TD 16 will limit the storm's ability to rapidly intensify. TD 16 resembles the "monsoon depressions" common in India's Bay of Bengal or the Western Pacific. A monsoon depression is similar to a regular tropical depression in the winds that it generates--about 30 - 35 mph near the outer edges (and usually stronger on the eastern side of the circulation.) Monsoon depressions have large, calm centers, and can evolve into regular tropical storms, if given enough time over water to develop a tight, closed circulation. Today's monsoon-like depression in the Caribbean was able to form because the atmospheric flow pattern of the Eastern Pacific has shifted eastwards into the Western Caribbean, bringing in the Eastern Pacific ITCZ (Intertropical Convergence Zone, a region of converging surface winds that creates a band of strong thunderstorms). This unusual flow pattern is forecast to remain in place for at least the next ten days.

An Air Force hurricane hunter aircraft has been flying at 700 feet in TD 16 since 1:30pm EDT, and has thus far found a central pressure of 999 mb. The strongest winds at flight level seen as of 3:20pm EDT were 32 mph, located about 100 miles east of the center of TD 16. Surface observations show that the strongest winds at any surface station continue to be at Buoy 42057, several hundred miles to the southeast of TD 16's center. Winds were 27 mph, gusting to 34 mph at 2:43pm EDT this afternoon. Rotation of TD 16 can be seen on radar loops out of Pico San Juan, Cuba, and well as satellite imagery. The heavy thunderstorms are currently quite disorganized, but a curved band is beginning to wrap around the north side of the center, signaling that TD 16 is growing more organized. TD 16 has brought torrential rains to the Cayman Islands, Jamaica, Cuba, and Honduras today.

Forecast for TD 16
Because TD 16 is so large, it will take more time than a typical depression for it to spin up into a strong tropical storm. Given that the steering currents are expected to pull TD 16 north-northeastwards over Cuba and into South Florida and the western Bahamas on Wednesday, the storm lacks sufficient time over water to be any stronger than a 50 mph tropical storm for Florida. TD 16 is organizing pretty slowly this afternoon, and I think the top winds in Southeast Florida are most likely to be in the 25 - 35 mph range on Wednesday. Winds are likely to be stronger in the western Bahamas, perhaps 30 - 40 mph, since they will be in the stronger right front quadrant of the storm. By the time TD 16 makes landfall in South Carolina or North Carolina on Thursday morning, it could be as strong as a 50 - 60 mph tropical storm. However, wind shear will increase sharply on Thursday as TD 16 gets caught in an upper-level trough of low pressure, and NHC is giving TD 16 only a 9% chance of making it to hurricane strength before it becomes an extratropical storm on Thursday. The primary danger from TD 16 is not wind, but heavy rainfall. A potent upper-level low and stationary front over the U.S. East Coast have been pulling moist, tropical air from the Caribbean northwards over the past few days, bringing heavy rains that have saturated the soils. This is called a Predecessor Rain Event, or PRE, since it comes in advance of the actual rain shield of the storm. (A PRE from Hurricane Karl brought southern Wisconsin the heavy rain that caused the levee on the Wisconsin River to fail yesterday.) Wilmington, NC received 10.33 inches of rain yesterday, its second greatest one-day rainfall since record keeping began in 1871. Only the 13.38" that fell during Hurricane Floyd on September 15, 1999 beat yesterday's rainfall total. With TD 16 expected to bring another 6 - 8 inches of rain to the region later this week, serious flooding is likely, and flash flood watches are posted for the North Carolina/ South Carolina border region. South Florida is also under a flood watch, for 3 - 5 inches of rain. Flooding rains of similar magnitude can also be expected in Cuba, the Cayman Islands, and the Western Bahamas through Wednesday night. Both the GFDL and HWRF models are predicting that TD 16 will dump rains in excess of eight inches along narrow portions of its path in eastern Florida, South Carolina, and North Carolina.

Up to 1,000 feared dead in Mexican landslide
Mexico has taken the brunt of the devastation from the hurricane season of 2010, thanks to the landfalls of this year's two deadliest and most damaging storms, Hurricanes Alex and Karl. But Mexico's worst blow yet hit this morning, when heavy rains from the remnants of Tropical Storm Matthew triggered a landslide in Mexico's mountainous Oaxaca state that buried as many as 1,000 people in Santa Maria Tlahuitoltepec, a town of 9,000. Rescuers have not reached the area yet, but hundreds are feared dead in the 300 homes that were buried by the early morning landslide. Matthew hit Belize on Saturday as a minimal tropical storm with 40 mph winds, and dissipated Sunday over southern Mexico. However, Matthew's remains stalled out over the region of Mexico that had already received torrential rains from Hurricane Karl, which hit on September 18. Satellite estimates of Matthew's rains over southern Mexico (Figure 3) show that a foot of rain may have fallen in the landslide area. Matthew's remains still linger over the region, but are probably only capable of bringing 1 - 2 inches of additional rain through Thursday.

Elsewhere in the tropics
Once TD 16 moves out of the Caribbean, the GFS model predicts that the Western Caribbean will "reload" and produce another tropical disturbance capable of developing into a tropical depression early next week. The GFS also predicts a tropical or subtropical storm will form over the Bahamas late this week, and move north-northeast along the U.S. East Coast, missing hitting land. The NOGAPS model hints at the Bahamas storm, and also predicts development of a tropical wave a few hundred miles northeast of the Lesser Antilles Islands, about a week from now.

Hottest day in Los Angeles history
The mercury hit a blistering 113°F (45.0°C) at 12:15 pm PDT yesterday in downtown Los Angeles, making it the hottest day in Los Angeles history. It may have gotten hotter, but the thermometer broke shortly after the record high was set. The previous record in Los Angeles was 112°F set on June 26, 1990; records go back to 1877. Nearby Long Beach tied its hottest all-time temperature yesterday, with a scorching 111°F. And Christopher C. Burt, our new featured blogger on weather records, pointed out to me that a station in the foothills at 1260' elevation near Beverly Hills owned by the Los Angeles Fire Department hit 119°F yesterday--the hottest temperature ever measured in the Los Angeles area, tying the 119°F reading from Woodland Hills on July 22, 2006. Yesterday's record heat was caused by an unusually large and intense upper-level high pressure system centered over Nevada that generated winds blowing from the land to the ocean, keeping the ocean from exerting its usual cooling influence. Remarkably, Los Angeles had its second coldest summer on record this year, and temperatures just five days ago were some the coldest September temperatures in the region for the past 50 years.

The remarkable summer of 2010
Wunderground is pleased to welcome a new featured blogger--weather historian Christopher C. Burt. Chris is a leading expert in the U.S. on weather records, and is author of the world's most popular weather records book published to date, Extreme Weather: A Guide and Record Book. He's spent a lifetime collaborating with like-minded individuals from around the world, and no one--including official sources such as the National Climatic Data Center and the National Extremes Committee--has done as thorough a job correlating the various weather records available and determining the most accurate extreme values of such. Each month he'll be reporting on the notable records for heat, cold, and precipitation set world-wide, and his first post takes a look at the remarkable summer of 2010. It's great to have someone like Chris who stays on top of weather extremes, and I hope you'll pay a visit to his blog and welcome him to the wunderground site!

Is that associated with TD 16? Is it really THAT far displaced. It looks like a 60 mph ts my itself, jajaja.
Could the center reform there? If not why not? Thanks.

Not trying to be a hype-caster, portions of FL may see 10+ inches of rain.


That could absolutely happen, even in a good afternoon thunderstorm we can get 2-3 inches. I'm thinking that the areas that will see that much rain will be more towards the central florida area, due to the rain received from the front, then the tropical rains.

So far tonight in my part of Dade County we haven't had a lot of rain. Been in the dry spot!

Sometimes that happens from the way the swaths of rain move across, you just end up where the rain isn't.

Hi everybody, Lake Worth here, SE Palm Beach County, FL. Winds picking up, we've already had some minor flooding tonight.
I'm looking forward to a Fay or Ernesto-type storm, we need water badly :)
However, as nash wisely said, NOOA weather radios on alert mode for possible tornadoes. For those who are new here and think this will be no big deal (I hope they are right), I warmly recommend to be safe by listing to the advisories and please, do not drive on flooded roads. Remember that TS Fay killed people who didn't heed the warnings and either went surfing or drove their vehicles to flood areas thinking there was a road beneath their car and got stuck. It's not the wind that'll be the biggest threat, it's the rip currents and flooding when you can't see where the road is and you'll might get into trouble.
Stay safe and prepared, every storm is potentially dangerous, STD, TD or a named storm will spawn unexpected tornadoes more often than than not.
Thanks for all the great info you're posting on this blog :)


Get real. Nobody drowns in flooded intersections in south Florida; the terrain is flatter than the proverbial pancake. To be sure water can get deep enough to kill your car's ECU, but not deep enough to drown anyone who isn't bent on suicide.

I've lived in south Dade for more than thirty years; I lived through 24 inches of rain from tropical storm Dennis in the early 80s, watched Andrew rip the roof off my house in 92, made it through the downpours of Irene, Katrina, and some nameless storms, and nobody, I repeat nobody, drowned in their car down here.

Overhyping a minor storm is just as bad as pooh-poohing a major hurricane. A poorly organized depression that may throw six inches of rain our way is a peace offering from the weather gods; when they want to kill, they know how to do it.

Good evening,

It seems like the wave at 45W seems better organized than TD16.
Wind Shear is a low 5- 10 knots with an anti cyclone starting to form, if I am reading the map correctly.
However,the 850 mb Vorticity Map shows that the vorticity is lacking.

Those are just my thoughts. Obviously, TD 16 takes priority but this could be a bigger deal in the future.

People in the Islands are watching the action out there for sure.
A lot of potential, but the NHC is not too concerned in the 48hr time frame.

Exactly what I said. :)

Just sayin' one point does not make it, that's all.

If there were a 25% part of that area having 1020, say...

As I said, all obs I saw from that entire area was around 1000.

Remember, too, that recon was at 1000 most of its flight.

Again, think that was high too. It is extrapolated after all. Same as xtrap, lol.

I'd have to say that the lesson to be learned here is not to get hyper over the 7-14 day out models. 7-14 days ago we were looking at a Category Catastrophe Hurricane and instead it looks like a Category zero possible rain and flooding event. Those computer spitballs didn't hit their target, this time. Those pesky models appaantly failed to measure the strength of the trof. Perhaps some actual obs from long-range G-IV missions might have helped improve the model output.


Cosmic,
I think the models did not have the handle on the Caribbean monsoonal trough flow and its multiple low pressure areas and ended up spewing out TCs from this confusion. Nice the SE trough reached as far down as it did and maybe reached further than modeled.

Got a question for your hurricane savvy folks.

I have notice, that the remnants of Julia, are moving to the Northwest away from Bermuda. Is it possible that the remnants might get caught up in the frontal system which lies off the east coast, and over the gulf stream, and possible regenerate? And if so, would this have any bearing as to the possible track of Nicole?



Julia won't be able to regenerate, as conditions aren't supportive of that. TD16/Nicole's track won't be altered as a result.

Evening everyone.

If you look at the graphic Bordonaro posted 1313 - you will see that the severe weather north of Dade county is from the front that is providing the pathway for TD16.

The rain is magnified by the tropical moisture to the south, leading to the unstable atmosphere. As most know, just the passage of a cold front can cause the kind of weather that is happening, especially north of West Palm.

Not a good setup, because those that already have the rain from the front, will be getting more from TD16/TS Nicole tomorrow.

I agree 100%..How can we make the point clear. It is like having a strong cold front and a tropical system in one, this may get rather UGLY!!

Not yet, it is the deep tropical moisture being rammed and lifted in front of that stationary front draped across FL.

It will get much worse tomorrow, as the TD 16 will be approaching from the south. The moisture fetch gets lifted up in front of the stationary front. It may be the worst is offshore east of FL, however that stationary front and deep trough to your west will create its own heavy rainfall regardless of TD 16.


Thanks for the reply. That front brought us some rough stuff here in Panama City Sunday night into Monday morning.

Considering how far away from the center the higher winds are, I am thinking even Cat 1 might be a stretch. From the way it has been reported, the winds that are close to TS are pretty isolated and well away from the center.

I just don't see it happening, unless the structure of the storm changes dramatically.

Yeah, I agree with this.

Bad cold front? It's pretty much a dead cold front. This front is on the other end of the spectrum from the one that came through with Wilma. In fact, it seems to be moving backwards, to the NW, the last few hours.

Also, kinda goes to my "calibration" of recon. They had 1001mb at GC while you, and other surface obs were showing 998mb at the time.

I believe the coc is really 995mb as of the last update because of just that.
