Floods and monsoons
FLOOD warnings are still in place for Daintree and Mossman rivers, after expected heavy rains last night over the Daintree river catchment.
The officer-in-charge of the Cairns Bureau of Meteorology office, Greg Connor, said it is a minor flood warning and the final one with levels slowly easing below the flood levels.
‘‘At this stage we are not anticipating floods warnings to continue over the weekend, however, the situation could change depending on the amount of rainfall (from last night) so keep a watch on the situation,’’ Mr Connor said.
‘‘Over the next three days for your area (Douglas) we are expecting mostly moderate falls.’’
Mr Connor said the reason for the monsoonal trough was because of the ex-tropical cyclone Fletcher situated in the Gulf.
‘‘Even though the current major low systems are a long way from the Daintree area, it has an indirect effect from the ex-cyclone Fletcher, which is dragging lots of moisture in over the eastern tropics causing increased rainfalls,’’ he said.
‘‘Because the monsoon trough is so active there are a number of small lows near the major systems and when you get lows near to each other they tend to rotate around each other and sometimes they do merge.
‘‘Reports of ‘ Super cyclones’ are unwarranted, we believe these systems in the Gulf will stay relatively weak even though it’s bringing high levels of rainfall.’’
Mr Connor said while this is an active phase of a monsoonal trough, the Bureau of Meteorology are predicting there will be more troughs and it will not be the last this summer.
‘‘Monsoonal troughs tend to occur every 30-40 days, so we are expecting at least another surge of the monsoon in late March,’’ he said.
