Interesting hybrid low set to drench Spain's Canary Islands

An interesting 1002 mb low pressure system with some characteristics of a tropical storm has developed off the coast of Africa, a few hundred miles west-southwest of the Canary Islands. An ASCAT pass from last night revealed top winds of 40 mph near the center, so the low is probably near tropical storm strength. This low is moving east-northeast towards the Canaries, and will likely bring sustained winds of 30 - 35 mph, gusting to 50 mph, to the islands tonight. The storm formed over the weekend from an isolated cold-cored low that was wandering over the Atlantic, and phase space analyses from Florida State University revealed that the low developed a partial warm core over the weekend. A respectable amount of heavy thunderstorm activity has built near the storm's center, characteristic of a tropical storm. The low is over cool 21 - 22°C water, far colder than the typical 26°C needed for a tropical storm to form. These SSTs are about 1 - 2°C warmer than usual for this time of year. Wind shear is marginal for tropical storm formation, about 20 knots. The comma-shaped structure of the storm's spiral bands is characteristic of an extratropical cyclone, and it is pretty unlikely that NHC will view this hybrid storm as being sufficiently tropical to warrant naming it a subtropical depression or subtropical storm. The low is headed towards colder waters of 20°C that lie near the Canary Islands, and the system should become less tropical today.


Figure 1. Hybrid 1002 mb low approaches the Canary Islands, in this visible METEOSAT image from 7am EST 2/1/10.

You can use our wundermap for the Canary Islands to watch the storm roll through the islands. There are two web cams to watch (currently showing thick clouds) that might be interesting. EUMETSAT satellite images loops will also be interesting.

Are there shelters open? Are homes getting wet inside? or is mainly water in the streets. Local Miami news web sites have poor info about this too.


No, I haven't heard of shelters, but the roads have flooded all over. A few feet of water in some places. A number of homes have had roof collapse but nothing too serious. More rain coming though.

Isn't is nice the blog is throwing a "Pity Party" for me. They are just a bunch of "wild and crazy guys" these bloggers. They will do anything for laugh.

Funny that you mention that because many people here are saying the same thing. We don't even get these amounts during the rainy season. Very unusual, but not uncommon in an El Nino year. Some of the places have received enormous amounts of rain all over South Florida and hardly a mention.

Graziers rejoice as rains drench southern Qld

The remnants of tropical cyclone Olga have delivered big dividends for graziers in south-west Queensland, with some of the state's most drought-affected country soaked in recent days.

ABC reporter Paul Lockyer has been travelling through the region in a helicopter.

"After delivering big falls around central Queensland, we tracked the rainfront as it spread west from Thargomindah to Durham Downs on the Cooper Creek," he said.

"We later flew through even heavier rain as we travelled up the Cooper to Windorah.

"Steady, soaking rain continues to spread to the south-west towards New South Wales and South Australia."

It is a new year bonus for graziers on top of Christmas rain.

Steady falls have been reported in south-west Queensland around Thargomindah and Quilpie, while Charleville has had its best rain in 16 years, recording 114 millimetres to 9am AEST yesterday.

Thargomindah resident Andrew Hughes says graziers are thrilled because they have battled drought for almost a decade.

"It's been unbelievably dry so it's good to finally get a wet year - everything is sort of bouncing back a fair bit," he said.

"With this steady rain we hope that the red country is going to really come good - it's nice to wake up and see green everywhere."

Mr Hughes says frogs have also become a common sight on water-logged properties.

"We've got a heap of swamps on our place - some of the bigger ones are four kilometres wide, so it is unbelievable seeing the wildlife on them and the greenery around them," he said.

"God the frogs ! You can't walk anywhere at the moment without seeing a frog out in the middle of the paddock.

"They are breeding up at the moment too so they are making lots of noise."

The heavy rain forced the closure of some roads at Roma.

More than 130 millimetres has fallen in the Roma region in the last 48 hours and parts of the Carnarvon and Dawson Highways are cut.

State Emergency Service volunteers are sandbagging along Bungil Creek in Roma as a precaution.

Meanwhile, new figures show despite some heavy rainfall over the past two days, average falls for the Wide-Bay Burnett in south-east Queensland were down for January.

Rainfall at Hervey Bay Airport in January was down almost 70 per cent on last year with only 59 millimetres.

Average temperatures were up slightly for the region, with Gayndah recording 33.3 degrees Celsius, up 0.5 degrees for January.

Queensland Climate Services manager Dr Jeff Sabburg says it was a relatively dry month for the region.

"It usually gets 174 millimetres in January - it only came in at 59 millimetres for January of this year and similarly for Gayndah Airport, only 37 per cent of its average, which is 113 millimetres.

"It came in at 42 millimetres so both those being similar and below average."

Olga to rain on drought-ravaged NSW


Ex-tropical cyclone Olga has dumped heavy rain on some parts of Queensland as it drifts south towards NSW.


Farmers in New South Wales hope the remnants of ex-Tropical Cyclone Olga will keep heading south, bringing much-needed rain.

Some graziers in the far north-west of the state are still battling years of drought. While the rivers in the northern Murray-Darling catchment are running again, it is only a moderate flow so far, and follow-up rain is still needed to soak the parched outback landscape.

It has been 10 years since the last major flood hit north-western New South Wales but the recent rain in Queensland has now made it over the border and the rivers are running again.

The moderate flow is welcome for grazier Murray McClure from Trevallyn Station.

"Look at that new life, the growth in those trees, all in a matter of days," he said. "I bet they're loving it. We're loving the sight of it too."

The Darling River may be flowing but Trevallyn Station has not had decent rain for almost a year. Neither has a lot of the area in the north of the Murray-Darling catchment.

Mr McClure's property is still in the grip of an horrific drought. The red dust landscape is sunbaked and the feed cover is long gone.

He has had to destock and he is now hand-feeding the few sheep that remain.

"All the cattle have gone three or four months ago," he said.

"A few months ago the best of the ewes, they are all away and joined with rams, so hopefully it'll rain and we'll be able to bring them home for lambing."

But it is better news for irrigators. The recent flows have restored water allocations for those growers around Bourke in far-western New South Wales.

Bourke Mayor Andrew Lewis says after years of heartache, they will be able to finish their summer crop and have a winter crop as well.

"Anybody [who] got the good rain should be right through to spring," he said.

"A few more little follow-ups, we could do with an inch, now just to freshen the top up, but that is probably getting greedy. People out there, they need four or five inches. It'd be good."

That wish could be granted, with the Bureau of Meteorology predicting good rain in the Darling catchment over coming days and potentially as far south as the Riverina.

At Mark Etheridge's property near Wilcannia in north-western New South Wales, the children are enjoying swimming in a river that was once a dry bed.

But his property is still parched and while he is overjoyed to see the Darling River running again he says a lot more water is needed if this outback landscape is to return to a healthy state.

"This flood doesn't stop the drought," he said.

"It alleviates the symptoms in the river as you can see. The trees are putting on new growth. They are very happy. It is doing a wonderful job but it's far from over.

"The floodplain really needs to get wet to survive properly and that won't happen this time but gee, who knows, it may happen next month, next year."

Weather improves, but more storms to come

The Bureau of Meteorology (BOM) says, while weather conditions have largely eased today in Queensland, more thunderstorms are expected later in the week.

About a dozen Gold and Sunshine Coast beaches in south-east Queensland were closed yesterday due to big seas and dangerous surf whipped up by ex-tropical cyclone Olga.

Chief Lifeguard Warren Young says Coolangatta and Palm Beach have been shut this morning and the situation will be reviewed throughout the day.

BOM senior forecaster Brian Rolstone says low-level monsoonal conditions have moved south, but higher circulation is causing the rough conditions to remain.

"At the moment, the weather will wind down over the eastern districts, but it'll come back in the form of rain and thunderstorms across southern Queensland on Thursday and Friday," he said.


A severe weather warning is still current for the Capricornia district and the far southern areas of the central highlands and coalfields.

BOM forecaster Mike Marinan says southern parts of Rockhampton received about 130 millimetres of rain overnight.

He says Rundle Island recorded the strongest winds overnight, with gusts of more than 100 kilometres per hour.

"The area of concern through today in the next 24 hours would be from about Rockhampton and south," he said.

"That's where the heaviest falls should occur."

"Wind conditions are still remaining quite strong with that severe weather warning current, particularly about southern central highlands - to the south of that decaying tropical cyclone Olga which is slowly moving south-west now and also through the coalfields and Capricornia," he said.


Central Queensland drivers are being warned not to try to cross flooded roads after a number of swift water rescues.

Authorities say two people managed to get themselves to safety after they got caught in a causeway south-west of Calliope near Gladstone early this morning.

Queensland Fire and Rescue Service (QFRS) officers also helped drivers stranded at Bouldercome and Stanwell.

Emergency Management Queensland (EMQ) spokesman Robbie Medlin says too many motorists are taking risks on flooded roads.

"I think people are underestimating the depth of the water and the flow of the water, and are assuming that the vehicle that they're in is capable of crossing that particular floodway that they're trying to go through," he said.


Rockhampton Regional Council mayor Brad Carter says, once the weather starts to improve, clean-up work can begin.

Councillor Carter says the deluge flooded roads, brought down trees and caused beach erosion throughout the region.

"We believe that the conditions will improve as the day goes on, but we do express a need for caution because of some potholes and some wash-outs that could be evident when the water recedes," he said.

"Our team of engineers and council officers will be inspecting those roads throughout the day."

In the central-west, Charleville Cosmos Centre spokeswoman Jane Morgan says European tourists visiting the region are surprised by the cool and wet conditions during the middle of summer.

"They say we came to see the red dirt and the heat and we've only had two days of heat - of anything even approaching 40 degrees - and now all of a sudden it's cold and green," she said.

"We get a lot of Scandinavians and Germans and they come out specifically to see the red dust and the dirt and the flies - you know they are just fascinated by it."

The Australian Flood Plain Association (AFPA) says rain and more flooding in Queensland's Channel Country will not just benefit graziers, but the region's tourism sector as well.

AFPA spokeswoman Karen Tully says, for the second year in a row, floodwater from Queensland is flowing towards Lake Eyre in South Australia.

She says more visitors may travel to see the inland river systems in flood.

"All our indicators are our numbers will be enhanced on last year ... particularly in Charleville and in Longreach and in Birdsville," she said.

"There was something like 30,000 tourists visited Innamincka [in South Australia].

"All our predictions are there will be greater number of visitors to our area."
