Well not today but in the recent week or so.

Cyclone outlook points to late La Nina:

The Bureau of Meteorology has released its Tropical Cyclone Seasonal Outlook for north west Australia.

The season runs from November 1 until April 30.

The bureau's Andrew Burton says climate models are trending towards another La Nina episode.

He says there is a 60 per cent chance of an above average number of cyclones, with the average being five.

"Climate models are trending towards a late developing La Nina, so it's really not like last season when we had a very strong La Nina signal," he said.

"The waters around north-west Australia are not yet warmer than usual unlike last season but we do expect that we will develop warmer waters as we get into December, so we do expect that perhaps we may end up with above average numbers."

Northern Wet Season 2011/12

And it's been raining at Argyle. 6mm over night. I know it's not much, but it's an indicator that the seasons have changed. Not and humid, I am told. Lovely - not.

Residents warned to be flood ready:

The head of Western Australia's flood warning centre says many north west communities are vulnerable to the type of flash flooding that destroyed dozens of homes last wet season.

Senior emergency planners gathered in Broome yesterday to discuss preparations for the upcoming wet.

Among those to attend was Graeme Ezzy from the flood warning centre.

He says this year's devastating floods in Warmun show it is impossible to know when a flood may hit, so residents should be on alert throughout the season.

"We've got to be aware of the environment we live in everywhere in the Kimberley, because it's not benign," he said.

"The probability of having one of these extreme events is not high but as we saw in Warmun, the consequences of these events can be very high."

Parched parts of WA and the NT get a soaking:

A broad region of low pressure is triggering rain and storms across the parched Kimberley and northern Interior and over western parts of the NT.

In the Kimberley, Kalumburu picked up a daily total of 21mm to 9am with storm activity. This is the heaviest rain since April. Uluru picked up 20mm to 9am bringing the monthly total close to 60mm and over 3 times the October average.

Now that storms are bringing heavier rain, bushfires caused by lightning are becoming less likely to occur.

Thunderstorms over the region have the potential to be severe today due to the risk of flash flooding and damaging wind. Large hail is a chance in southern-most parts.

Strong winds in the upper atmosphere may reach the surface with storms over coming days. There is also plenty of tropical moisture available to storms, meaning that heavy falls with storms are likely.

Storms will continue over WA and the NT next week, although will push further north under the influence of a high pressure system ridging in from the south.

Another low pressure trough will move in from the Indian Ocean, bringing rain and storms to the west coast from late Wednesday.

Residents warned to be cyclone ready:

The State Emergency Service (SES) says residents in north-west Western Australia should be finalising their preparations for the cyclone season which officially starts tomorrow.

Residents are being urged to ensure loose or bulky items which could be thrown around during a cyclone are stored away or secured.

Trevor Patton from Karratha SES says people should also have emergency kits and evacuation plans on stand-by.

He says forward planning can relieve some of the pressure if a cyclone does occur.

"It just takes the extra stress off you, if you leave it until we are on a yellow alert, it just adds a bit more stress on the individuals trying to make sure they've done those last bits and pieces," he said.

Heavy rain soaks WA
Douglas Fenton, Tuesday November 1, 2011 - 12:23 EDT

The heaviest rain in half a year has soaked parts of WA, from the Kimberley to the Gascoyne.

There were scattered daily falls of 10-50mm across these districts to 9am on Tuesday. The heavy rain has been triggered by a lingering low pressure trough and amplified by an upper level cold pool.

Yarrie in the Pilbara picked up one of the highest 24 hour totals with 48mm. Telfer gained 30mm, this is their heaviest daily rain for November in 7 years and the heaviest since April. Meekatharra in the Gascoyne gained 22mm to 9am, which is twice the November average total rainfall and the wettest November day in 28 years.

Patchy rain and potentially severe storms will continue over the region today and tomorrow, with heavy falls likely in parts. Storms bring the risk of flash flooding and damaging winds.

A low pressure trough will push in from the west on Thursday, generating rain over the South West Land Division. Perth can expect rain on Thursday and Friday, with the heaviest falls expected on Thursday due to likely storm activity. Plenty of available moisture brings the risk of flash flooding and a strong jetstream brings the potential for damaging winds.
