atlantic Hurricane Humberto

[Somerset Squall]

At last, a hurricane! Humberto is a 65kt hurricane this morning. The hurricane has well developed banding and deep central convection. There isn't a well defined eye yet but one appears to be developing slowly. Humberto has another day or so to strenghen before the northward track brings it over cooler waters. Humberto should turn back westwards as the trough to the north is replaced with a ridge.

Humberto the hurricane!

Tropical storm Humberto upgraded to category 1 hurricane

 

Humberto becomes first Atlantic hurricane of the 2013 season after strengthening north-west of Cape Verde islands

 

 

Tropical storm Humberto has strengthened to a category 1 hurricane far out in the Atlantic, becoming the first hurricane of the Atlantic season. Humberto's maximum sustained winds early on Wednesday were almost 75mph (120kph). The US National Hurricane Centre said the hurricane could gain more strength before a weakening trend is expected to start on Thursday.

 

Humberto is centred about 310 miles (500km) west-north of the southernmost Cape Verde islands and is moving north-northwest at a rate close to 8mph (13 kph). Tropical storm Gabrielle is passing west-south of Bermuda, hitting the wealthy British territory with wind, rain and rough surf. Gabriella has maximum sustained winds of almost 60mph (95kph).

How tardy!

 

 

Humberto grew to hurricane force far out in the Atlantic on Wednesday, becoming the first hurricane of the Atlantic season, while Bermuda shook off a drenching by Tropical Storm Gabrielle.

 

Humberto's maximum sustained winds were near 85 mph (140 kph), but the U.S. National Hurricane Center said some weakening was expected over the next two days. The storm was centered about 395 miles (630 kilometers) northwest of the Cape Verde Islands just before midnight EDT (0400 GMT) and was moving northward at 13 mph (20 kph) into the open Atlantic.

 

In Bermuda, Gabrielle caused several power outages overnight, but no major damage was reported on the British territory. The government announced that all public schools were reopening and there would be sporadic ferry service. The island's meteorology service warned that strong winds and rain would continue to pelt Bermuda as the storm headed north.

 

By late Wednesday, Gabrielle had weakened to a tropical depression and was about 135 miles (220 kilometers) west-northwest of Bermuda with sustained winds of35 mph (55 kph). It was moving westward at 6 mph (9 kph), and was predicted to pick up forward speed. It was expected to turn to the north-northeast and remain well off the U.S. East Coast while heading toward a possible weekend brush with Nova Scotia.

 

It is unusual for this much time to pass in the Atlantic season without a hurricane forming, though not unheard of. Hurricane Gustav was the first of the 2002 season when it formed on Sept. 11 of that year. The record for the latest first-of-the-season hurricane is Oct. 8, 1905, based on records dating to 1851

85mph now, should last a while and will possibly strengthen again so good for the ACE total.

How lacklustre this one has been:

 

 

Hurricane Humberto Likely to Weaken Soon

 

The National Hurricane Center says the Category 1 storm has maximum sustained winds late Thursday near 80 mph (129 kph), with weakening forecast over the next two days.Humberto is centered about 630 miles (1014 kilometers) northwest of the Cape Verde Islands and is moving north-northwestward at 12 mph (19 kph). 

 

Meanwhile, Gabrielle (ga-bree-EHL') remains a tropical storm but is expected to weaken as it moves north-northeastward after drenching Bermuda. The storm's maximum sustained winds are near 40 mph (64 kph).Also Thursday, a tropical depression has formed in the southern Gulf of Mexico with sustained winds of 35 mph (55 kph). It is expected to dump 10 to 15 inches of rain over a large part of eastern Mexico with 25 inches in some places.

Hurricane HUMBERTO: Probability of Cat 1 or above winds to 117 hours lead

 

[Sainsbo]

Ming be interesting to watch:

 

 

 

Quite a lot of agreement currently that Humberto may swing towards, or close to the UK. It will have turned extratropical long before it gets to us, but just look at the intensity readings:

[Somerset Squall]

After Humberto's 75kt peak, it has weakened under heavy shear. Winds are down to 55kts, so Humberto has lost hurricane status. A turn back west will occur soon, and shear should eventually ease. NHC forecast Humberto to eventually regain hurricane status by day 5 as it turns north for a second time in the middle of the Atlantic.

[Coast]

[Somerset Squall]

Humberto is no longer a tropical cyclone, and has been declared a remnant low. The LLC has been devoid of convection all day which has caused the downgrade, but the centre is still well defined, which means when shear lessens and waters warm again along track, ex-Humberto should regenerate.

[Coast]

Humberto really didn't make much impact as the first Hurricane of 2013!

[Somerset Squall]

Convection is increasing over the remnant low of Humberto this evening. If this persists, then Humberto could regain tropical cyclone status this evening.

[summer blizzard]

With a well defined circulation and TS force winds i suspect that we are just waiting for convection over the center to enable a mid-level circulation to develop (how strange that we need to go bottom-up this time).

 

[Somerset Squall]

Humberto has been re-upgraded to a tropical storm this afternoon, as convection has persisted near the LLCC. Some strengthening is expected before a trough lifts Humberto northeastwards out of the tropics at day 5. Humberto is forecast to become a minimal hurricane again.

[Coast]

It looks like Humberto won't be bothering the UK:

 

Tropical Storm HUMBERTO: Probability of tropical storm winds to 117 hours lead

[Storm Track]

Just maybe next week with the changeable or could still be bothering the UK with a post- tropical cyclone status early next week. There will be no longer to be a tropical storm status at this early next week.

[Somerset Squall]

Humberto may have become a subtropical storm according to NHC, though they have officially maintained it as a fully tropical storm as it is expected to transition back soon. The strongest winds are far removed from the centre, and the convection has moved to the peripheries of the storm too. Humberto has moved directly under an upper level low which may account for this rather unusual transition. The upper level low is expected to move away from Humberto tomorrow, allowing the storm to become fully tropical again.

Intensity is now 40kts. In light of Humberto's subtropical transition, it probably won't have time to become a hurricane again when it becomes fully tropical again. The environment is only conducive anyway for some modest intensification before Humberto races northeastwards out of the tropics and becomes extratropical in about 4 days time.

Humberto Weakens A Little

 

Tropical Storm Humberto’s winds decreased Tuesday night but is expected to strengthen again, according to the National Hurricane Center. At 11 p.m., the center of the storm was about 1050 miles west-southwest of the Azores. Humberto’s maximum sustained winds decreased from 45 mph to 40 mph at 11 p.m Tropical Storm Humberto is moving north-northwest at 7 mph.

 

Some strengthening is expected over the next 48 hours. Humberto is not threatening any land masses and there are no watches or warnings issued for this storm.

Tropical Storm HUMBERTO: Probability of Cat 1 or above winds to 69 hours lead

 

On that track, what remnants there are look likely to graze the UK, but it may be nothing worth worrying about

 

[Cookie]

We are forecast to get strong winds this weekend i this due to Humberto?

[Storm Track]

Humberto is now downgraded to be a tropical depression with the strongest of thunderstorms and showers.

Just tomorrow we will find it out what happened to see this tropical depression is going to heading toward the UK with some very strong winds from the remnant of Hurricane Humberto early this weekend or next week.

[Somerset Squall]

Humberto looks like it will dissipate soon. Intensity is down to 30kts, and the convection is very much lacking. If Humberto survives the extratropical transition, it will likely be absorbed by another extratropical low without coming anywhere near the UK. Humberto is unlikely to be the dominant system.

After a miserably windy and wet autumnal day for many of us, things are looking up by the weekend. From Friday onwards a settled spell is forecast - it'll feel a tad warmer and for the majority of us it'll be drier and brighter with plenty of September sunshine. This change in fortune is all due to a deep low pressure system - Tropical Storm Humberto.

 

 

As Humberto sweeps across the Atlantic, it'll weaken but will encourage a huge area of high pressure to become established across us, bringing relatively warm air from the Azores.bTemperatures will be nearer 20 or 21 degrees by the weekend - just a little higher than average for the time of year. This same area of high pressure (known as the Azores High) was responsible our hot weather through July. Hurricanes (and tropical storms) are most frequent during the months of August and September.

 

It's been a relatively quiet season so far - but we often get the remnants of these systems tangled up in our weather this time of year. More often than not, it means wet, windy conditions with gales. Tropical Storm Humberto is boosting warmer, drier air towards us instead.
