Heavy monsoon rain for the tropics this week

The monsoon season is in full swing this week, with repeated heavy rainfall forecast for much of northern Australia. Some parts of the Top End are likely to receive upwards of 300 mm this week, and weekly totals of over 100 mm picked for a large area.

The monsoon trough is currently sitting atop the country, with very moist winds feeding into it and triggering rain and thunderstorms. Over the next few days the trough will nudge south and a pair of low pressure systems embedded within it will generate widespread heavy rain.

These two low pressure systems, one off of the Pilbara coast, and the other near the Top End, have the potential to cause widespread heavy rainfall. They may even develop into tropical cyclones, with the low pressure system off of the Pilbara coast having the best chance to do so.

As the Pilbara low moves southward, it will draw huge volumes of moisture with it, potentially leading to heavy rainfall for the interior of WA.
