NORTHERN WEATHER PATTERN NEXT WEEK
Tropical Cyclone potential is VERY LOW next week but there is a HIGH potential for a tropical LOW to develop near the Kimberley coastline (so it needs monitoring). Overall the rainfall pattern between Monday and Sunday next week suggests wetter conditions over most of WA and central Australia. Below to well below average rainfall expected over most of Queensland next week except for the north tropical and Peninsula east coasts which can expect average or slightly above average rainfalls due to surface and mid level ridging.
NORTHERN WEATHER PATTERN FROM THE 5TH TO 11TH MARCH
Tropical Cyclone Potential remains LOW, Tropical LOW formation potential remains HIGH and the favoured area is well west of the coastline in the SE Indian Ocean. We see average to slightly above average precipitation values over most of Australia this week as the Queensland ridge breaks down and the monsoon trough begins re-appearing over northern and north-western parts. The trough is strongest over the NW (west of about Darwin) and so that area is likely to see the highest rainfall amounts. The only section of Australia expected to see dryish conditions is the northern Cape York Peninsula.
FROM THE 12TH TO 18TH MARCH
Tropical Cyclone potential increases to MODERATE TO HIGH particularly near the NW coast of Australia. Tropical LOW development potential is VERY HIGH. In this week we are anticipating a strong monsoon trough over the far north and north-west extending as far east as the NT coast and weakening, but still present as it heads into far north Queensland. We are expecting ABOVE AVERAGE TO WELL ABOVE AVERAGE rainfalls over most of the northern continent. Especially so over the NW coast of Australia.
FROM THE 19TH TO THE 25TH MARCH
We are expecting the Monsoon trough to peak in intensity over the Australian coastline therefore we are looking at a MODERATE TO HIGH potential for TC development this week, once again especially in the NW parts of the continent with potential increasing also in the Timor Sea and GOC. Once again the entire northern continent is expected to see above average rainfalls and particularly wetter than normal totals this week expected over the western Cape York Peninsula and the NW coast of WA. Please note that this is a VERY LONG WAY OUT AND SUBJECT TO MASSIVE CHANGES
NOTES ON THE MJO
The MJO signal is currently in the process of strengthening, we expect based on model guidance from a number of computer models that this moderate to strong signal will be maintained through phase 3 SE Indian Ocean and phase 4 Northern Oz before weakening in Phase 5 (Coral Sea) late in March. Consequently this strong MJO signal is likely to see the return of a vigorous monsoonal trough over north and north-west Australia with the weakening trough extending eastwards towards the Coral Sea in weeks 4 and then week 5 (last week of March) A new MJO may form and affect Australia late in April, however it's way too far to call at this stage.
