Finally, after a few months of cooling waters across the Central and Eastern Pacific, The Walker Circulation's worst kept secret has been revealed 'officially' at least (our subscribers have known this was coming since August). the Bureau this morning has upgraded us to a La Nina Watch as the threat of a developing La Nina has grown considerably. In saying that, don't go out and watch the latest Sci-Fi Weather blockbuster Geostorm and think that's what's about to happen in Australia, but th...
In what is one of our biggest upgrade of the past year. OCC subscribers now enjoy an Australian weather first. Our subscribers now have access to rapidly updating one-hour computer model data from the ACCESS-R model, the BoM's go to regional weather model for Australia. The computer model upgrade has been on the cards at OCC for a few months and was finally released live moments ago. Parameters such as hourly rainfall totals, surface pressures, surface level winds, surface...
G'day folks, I'm excited today to bring you some news of some different subscription plans available to our followers for the 2017/2018 season, including a no strings attached free trial. Instead of one plan for everyone, we have split our plans up into three and have also added a free 7 day trial for those who wish to trial what we offer with no risk. Check out our new plans below. To sign up head to www.ozcyclonechasers.com.au/subscribe Plan 1 - The Free Trial T...
In what has been thus far a very dry month across most of Australia, a couple of rain bearing systems will develop over the last couple of days of the month that may stop it from becoming Australia's driest June ever recorded. The first (and by far the largest) system is a cold front and associated rain band across SE Australia from today, but of more interest to our northern audience is a sharp increase in shower activity as we move into the weekend across the region from Rollingstone to G...
A major rain event is on the way for many Queenslanders later this week. Warm moist easterly winds from the Coral Sea will be uplifted at the surface by a surface trough moving SW from the ocean. At the same time, cold upper level air from a trough and upper LOW in South Australia will move east and create a sharp thermal gradient between the surface and the upper levels of the atmosphere. The combination of these two factors will result in some major dry season rainfall for coastal and inland p...
In the Aussie cyclone season that initially didn't want to begin and now doesn't want to end, a new LOW is set to form in the far North-Eastern Coral Sea and begin moving westwards later next week. Early indications are that the LOW will form along a trough line in the South-West Pacific Ocean. The exact origin varies from around the Solomon Islands through to Vanuatu but models are clearly intent on moving it westwards into the Coral Sea by next weekend. Of course, it is too early to spec...
The Joint Typhoon Warning Centre has issued a Tropical Cyclone Formation Alert for a Tropical LOW located well north of Darwin. A TCFA is issued when a significant Tropical Cyclone is expected to develop in the next 24 hours. The Bureau Of Meteorology have remained much more conservative instead adopting a MODERATE (20-50%)chance of Tropical Cyclone development in the next two days. The balance of available computer model evidence, particularly those models that are more reliable are showi...
Hot on the heels of TC Debbie, the tropics remain unstable. Multiple trough systems and atmospheric gravity waves are expected to pass across the far north of Australia over the next fortnight. Along these regions of enhanced instability computer forecast models are predicting from one, to as many as three LOW pressure systems to form. Thankfully these regions of cyclogenesis potential are nowhere near the areas that Debbie has just ravaged . However we need to be mindful that there will be...
