Amazing! It's Epsilon

By: Dr. Jeff Masters , 8:01 PM GMT on November 29, 2005

The official end of hurricane season lies only two days away, but the all-time records set by the Hurricane Season of 2005 continue to grow. Epsilon has become the 26th tropical storm of the season--far exceeding the previous record 21 storms seen in 1933. Epsilon may grow into the 14th hurricane this year, extending this year's record number of hurricanes to two more than the 12 hurricanes observed in 1969. Epsilon is really a hybrid between a tropical storm and a regular extratropical storm,
but its winds are nevertheless of tropical storm strength. Both Delta and Epsilon are more properly termed "subtropical" storms, but I guess the Hurricane Center has stopped calling storm "subtropical" to avoid confusion. Subtropical storms gain their energy not only from the warm ocean waters--like hurricanes do--but also from the release of potential energy created when cold and warm airmasses interact--like extratropical storms do. Epsilon is unlikely to strike any land areas, and will probably recurve to the north and east late in the week and be absorbed by a cold front sweeping over the north Atlantic Ocean.

Delta hits Canary Islands hard
Tropical Storm Delta slammed into Spain's Canary Islands last night at near hurricane strength, killing at least seven people. One man died when he was blown off the roof he was trying to repair, and six African illegal immigrants drowned after winds caused their boat to capsize while attempting to reach Gran Canaria Island. Twelve of the immigrants remained missing while 32 were rescued. Each year, thousands of migrants try to reach the Canary Islands from Africa and many die in the attempt, but usually not in a tropical storm!

Sustained winds of 71 mph gusting to 86 mph were recorded at Tenarife, and a wind gust of 94 mph was recorded at La Palma. The near hurricane force winds caused extensive damage to utility poles, roofs, and trees all across the islands, which are a popular tourist destination for Europeans. Power is still out to over 223,000 residents today, but is expected to be restored to a large majority by Wednesday. Delta weakened considerably after smashing through the Canary Islands, and came ashore in Morocco this morning with only 45 mph winds gusts and some isolated pockets of heavy rain. Delta's rains were expected to provide a boon to local farmers unaccustomed to heavy precipitation.

rwdobson: in reached a record 882 mb but only had max sustained winds of 175 mph because it was in an area of already lower pressure at the time. Normally, 882 mb would have max sustained winds approaching 200 mph.

Think of winds like a ball rolling down a hill. The speed of the ball is determined by the steepness of the slope, not by the final elevation at the bottom of the hill.

So for winds, the speed is determined by the pressure gradient--how much the pressure changes over a given space--not by the lowest pressure.

Is it me or does the water in the Caribbean and the Gulf look to be not only staying warm but getting warmer in the Gulf?

Big deal. When I was in Alaska, I saw the temperature go from 60 below to 40 above in 30 SECONDS! And that was the limit of the thermocouple used to measure the temperature. The temperature rise was probably much quicker than that.

The rise was caused by the sudden onset of the Chinook winds reaching speeds of up to 50 MPH. A couple hours later you could go outside and hear trees exploding!

To answer your question about these:
why would Tropical Storm Arlene have 70mph with a 989mb?

and Tropical Storm Cindy with winds at 70mph and a 997mb?

and Tropical Storm Delta with winds at 70mph and a 980mb?

Keep in mind that the winds speeds aren't merely the result of the central air pressure, but can also be a product of the pressure gradient force...that is difference between airpressures over a given distance. So take Cindy for example... rather high pressure for that windspeed. What that tells me is that this is likely a compact storm since the difference between it and say 1013mb would have to be very small to move air like that.

Now take Arlene. What that tells me is that this storm and its wind field were probably large in size which means that difference betweeen 987 and 1013 was covered by a much larger difference.

Hope I got all that right...

From what I can recall, we had hurricanes in DEC, JAN, MAR and May. Not sure about Feb or Apr.

They should just call it the high season and the low season for hurricanes, as it appears that tropical storms have formed or are capable of forming year round.

I wont be able to get that completed or even start honestly till the end of next MOnth most likely... I work a ful time part time (just a few hours a week) at the local weather office of a TV station and I have to make time to edit and produce five different Live Action Hurricane documentaries from this incredible season. Since this season doesn't seem to want to end, it doesn't leave me alot of time to work on my DVDS/Documentaries much less look for the footage you want...HOwever, I will definately get you all I have that you are looking for first chance I really get. This doesn't mention that I have a wife, a 4 and half year old precious little girl and my wife is 20 weeks pregnant with our second child which we just found out by ultrasound today that its going to be a boy.:)

In short, I will get it done for's simply a matter of when not if I will do it for you.:)

Hey David..I might be in the miniority here but I'm ready for this exhausting season to end..I've had to forecast , track and intercept the landfaling storms all year..the average of named storms for a season is roughly 10 for the years 1900 through last season... so basically we have already had two and a half seasons in one as far as named systems are concerned.. Before I worked in the Meteorological field...there couldn't be enough storms to develop to satisfy me

If I remember correctly..the list is for the 2005 hurricane season which although it ends on November 30th will follow the pattern of using this new list until January 1st 2006 if and when another Tropical storm forms. This was the case as mentonec in regard to the record setting two tropical storms that formed in December of 2003.

Another reference to this point is that the first ever tropical storm to form in April of that same year began with the first name of that seasons list hich was Ana.

it keep going and going and going well it ever end or well it go right in to the next hurricane year and what are the CH that we will see the Z storm and if this keep going will we down to the O storm or will we start wih are new for 2006 hurricane year like the A storm

12:06 AM GMT on November 30, 2005
Here is an interesting note, since we are all discussing the possibilty of this season extending past the artificial end of the Atlantic Hurricane season of November 30th.

What's the record for the most number of Tropical storms to form in December?

The answer is two in 2003 when both Odette that Dr. Masters mentioned in his blog and Peter (If I remember correctly, name might not be correct)formed only a few days thereafter.

I have an interesting thought, now I do expect for there to be some more storms such as Delta to form. But has there ever been any thought persay if we were to run out of names during a hurricane season, and subtropical season what would the response be as to naming sytems. Or would we just be naming them via numbers?

yovonc - Delta was no longer tropical when it hit Africa, so Delta doesn't count as making landfall in Africa. Not sure if there's been one before, though.

I'm near downtown Overland Park, 80th and Metcalf. We didn't get much wind, just some pea-size hail and rain. It was weird seeing lighting flashes over the Christmas lights that everyone has up.

torn, thanks for taking the time and energy to keep us informed on tornadoes. Now, when I press the F5 key (refresh) on my computer, I need to stpo for a sec, cause it reminds me of the red button to detonate some terrible disaster!

We had some wind and tornado damage near KC on Sunday as well. That was a very deep low that spawned the storms; the t'storms came in spiral bands. On the backside of the low were blizzard conditions, snow and 40-60 mph winds.
