Chris was born in Northern Greece and came to Australia as a young boy. He initially lived in Sydney and in 1988 was amazed by a very intense hail storm that smashed his house. This hailstorm had torn off the roof, blown out the windows of his house and left his family in complete shock, all with almost no warning. Since that day, Chris Nitsopoulos (Nitso) has been passionate about studying the weather and learning about what makes thunderstorms tick in order to better understand and forecast them. Upon completing his high school education in Townsville, he went on to James Cook university to begin a degree in Meteorology. Unfortunately Chris could not grasp the intricate mathematical formulas behind the physics involved in meteorology and changed degrees with a year left in his meteorology degree. He completed a degree in Secondary School education majoring in Geography and ironically enough, minoring in mathematics and physics. Nitso successfully taught Geography, Science, Mathematics and Physical Education for 5 years before dropping his full time teaching load to pursue a small business goal which could give him a lot more time off and help fund his storm chasing. In 2010, Nitso began a business selling sports shoes and supplements online. In 2013, Nitso shut down that business and now works primarily on Oz Cyclone Chasers and does a couple of days supply teaching at a couple of Catholic schools in Townsville The fact that his workload was far reduced allowed him to pursue his burning desire to chase tropical cyclones.



Even though Chris never completed his Meteorology degree, his passion for studying the weather and in particular severe weather systems has never diminished. During the dry season you would normally see Chris spending much of his spare time burying his head in old meteorology books or online researching meteorological studies from around the world. Chris enjoys and learns from every storm chase regardless of its success/failure, in fact Chris believes that in storm chasing you learn more from a failed chase or a failed forecast because it drives you to learn why you got it wrong and to strive to get it right next time. Chris is a registered storm spotter with the Bureau of Meteorology, he is a trained first aid officer and a qualified gym instructor. Chris also enjoys refereeing Rugby League and Rugby Union part time in the Winter months and says that he would go crazy with boredom and weigh 200kg if he didn’t have a hobby like refereeing to keep him fit and busy in the months between April and October.

THE WEEK AHEAD - PRE-MONSOONAL PHASE

Next week will be characterised by a pre-monsoonal weather pattern across Northern Australia. That means deep tropical maritime easterly winds will push scattered showers into tropical Queensland, while thunderstorm activity will become more active across the Northern parts of NT and the Peninsula of Queensland.  A monsoon trough will begin drifting southwards next weekend through the Banda and Java Seas and looks likely to spawn a weak LOW near the Top End coastline around Friday (16)...

WIDESPREAD HEAVY SHOWERS AND STORMS TO DEVELOP IN EASTERN QUEENSLAND

The combination of a deep moist easterly stream, a surface trough and upper trough are expected to create strong and widespread showers and thunderstorms across Queensland's Eastern half. rainfall totals above for the next 7 days suggest many parts of the state should receive more than 25mm (dark greens)with isolated parts in Central Queensland expecting over 100mm (yellows). There is likely to be severe potential with storms on Friday  particularly in areas that get some heating ...

BOM UPGRADE CYCLONE POTENTIAL FOR WA LOW

​Today's Cyclone outlook update from the Bureau of Meteorology in Western Australia has upgraded the potential for a Tropical LOW south of Bali to intensify into a Tropical Cyclone to Moderate by Thursday. That means it has a 2-5 chance out of 10 to become a Tropical Cyclone while it has a 5-8 chance out of 10 to remain a Tropical LOW.  Whether it becomes a Tropical Cyclone or remains a Tropical LOW, it is unlikely to directly impact the Western Australian coastline.  There are si...

TROPICAL LOW FORMS NEAR BALI AND MOVES INTO WA WATERS

Late yesterday a tropical LOW formed just to the south of Bali and has drifted southwards this morning to lie in Northern Western Australian waters. The LOW currently is situated in a favourable environment for further development but it is a very oval shaped (elongated) circulation therefore rapid deepening is not expected despite the reasonably favourable environmental conditions surrounding it.  The system is expected to drift either south or south-west and may deepen slightly over ...

TROPICAL LOW TO FORM ON MONDAY

A Tropical LOW is set to form on Sunday night or Monday near Java and track in a southerly direction into Western Australian waters during the week. The LOW will develop a little through the week and has been given a LOW (5-20%) probability of intensifying into a Tropical Cyclone by mid week. At this stage the LOW is not expected to hit the Western Australian coast even if it does form into a Tropical Cyclone, but it will set a chain reaction of events that should drag the monsoon trough southwa...

CORAL SEA CYCLONE POTENTIAL UPGRADED

The Bureau Of Meteorology has just upgraded the potential of the LOW South-West of the Solomons to develop into a Tropical Cyclone to between 20-50%, up from less than 5% yesterday. Basically that means given a similar type LOW in a similar environment we would expect a tropical cyclone to form between 2 and 5 times out of 10 whereas we would expect a Tropical Cyclone not to form between 5 - 8 times out of 10.  Yet again we need to stress that whether or not the LOW becomes Australia's firs...

CORAL SEA LOW FORMS WITH A BANG OVERNIGHT

CORAL SEA LOW FORMS WITH A BANG OVERNIGHT
​Overnight convection has exploded near the location of a developing Tropical LOW South-West of the Solomon Islands. The LOW which was expected to form on Friday night took its time to get started, but strong convergence formed along a trough line in the Solomons region yesterday and a small circulation formed south-west of the island nation overnight. Check out the 12 hour loop to see how the convective explosion took place. The system is likely to deepen a little over the next few days as...

CORAL SEA LOW BEGINS MOVING SOUTH-WEST

​A weak LOW and associated trough has begun moving south-west across the Coral Sea, but before you go and buy all the bread and milk that Coles, Woolies and IGA have in stock across SE Queensland, make sure you read the rest of this article.  The LOW is a part of a complex trough system and in itself is actually quite a weak feature. However the trough that the LOW is attached to has been creating heaps of heavy rain and strong winds to the LOW's south and East for a number of days now. You...

CORAL SEA LOW OVER THE WEEKEND

​The Bureau Of Meteorology today have mentioned that the Northern Coral Sea is expected to become more active this weekend with a Tropical LOW possibly forming in the north between PNG and the Solomon Islands. Initial indications are that environmental conditions will be unfavourable for intensification of this system and unfavourable for a Queensland track. The system is much more likely to track to the south or south-east.   Want to find out where it's going, why it's ...

MID LATITUDE CYCLONE BARRELS INTO W.A

An extra tropical cyclone/mid latitude cyclone is barelling into WA's Central Western coastline. The system is about to make landfall near Geraldton at time of writing (4PM QLD time). Unlike a Tropical Cyclone, a mid latitude cyclone harbours most of its worst weather away from the centre of the system. That is indeed the case with this system as well.  Looking at Western Australian radar and satellite below from the OCC Weather Centre shows us that most of the actual rain falling from...

WEAK TROPICAL LOW AND TROUGH TO FORM IN THE CORAL SEA

Late this week a weak Tropical LOW is expected to form in the far Northern Coral Sea or the Solomon Sea. The weak circulation is expected to move in a south to south-east direction. The system may deepen slightly over the weekend or early next week. At this early stage it is unlikely to intensify into a Tropical Cyclone and most likely to remain a weak LOW or wash out into a surface trough.  To gain access to in-depth daily video forecast updates on this and every other ...

The trough will clear the Central and Southern Queensland coast overnight tonight but linger through the Far northern Queensland region from approximately Cairns northwards. In the Territory, the trough will push rapidly north of Katherine and kick ...
