This system is very weak, so unless you get a rainshower, I wouldn't expect much in the way of wind.

TROPICAL CYCLONE ADVICE NUMBER 11
Issued by the Bureau of Meteorology, Brisbane
Issued at 4:34pm EST on Sunday the 24th of January 2010

The Cyclone WARNING from Cooktown to Cairns has been cancelled.

A Cyclone WATCH is current for the southern Gulf of Carpentaria coast and
islands from Karumba to Borroloola.

At 4:00 pm EST Ex-Tropical Cyclone Olga was located offshore from Cape
Tribulation.

Ex-Tropical Cyclone Olga has weakened and is now part of a vigorous monsoon
trough located across the northwest Coral Sea. It is expected to move west over
southern Cape York Peninsula and be located in the southeast Gulf of Carpentaria
by Tuesday morning when it is forecast to re-intensify.

A separate Severe Weather Warning has been issued for this trough system for the
Queensland east coast between Cooktown and Mackay.

People between Karumba in the southern Gulf of Carpentaria and Borroloola in the
Northern Territory should consider what action they will need to take if the
cyclone threat increases. If you are unsure about the actions to be taken,
information is available from your local government or local State Emergency
Service.

Details of Ex-Tropical Cyclone Olga at 4:00 pm EST:
.Centre located near...... 16.4 degrees South 145.6 degrees East
.Location accuracy........ within 110 kilometres
.Recent movement.......... towards the west southwest at 14 kilometres per hour
.Wind gusts near centre... 85 kilometres per hour
.Category........ below cyclone intensity
.Central pressure......... 997 hectoPascals

The next advice will be issued by 11:00 pm EST Sunday 24 January.

This warning is also available through TV and Radio Broadcasts; the Bureau's
website at http://www.bom.gov.au or call 1300 659 212. The Bureau and the State

TROPICAL CYCLONE ADVICE NUMBER 12
Issued by the Bureau of Meteorology, Brisbane
Issued at 10:54pm EST on Sunday the 24th of January 2010

A Cyclone WATCH remains current for the southern Gulf of Carpentaria coast and
islands from Karumba to Borroloola.

At 10:00 pm EST [9:30 pm CST] Ex-Tropical Cyclone Olga was estimated to be 50
kilometres east northeast of Cairns and near stationary.

Ex-Tropical Cyclone Olga has remained near stationary immediately off the Cairns
coast during the last several hours. It is expected to resume a westward track
during the next 6 to 12 hours and be located in the southeast Gulf of
Carpentaria by Tuesday morning. It may re-intensify into a Tropical Cyclone in
the Gulf of Carpentaria on Tuesday.

Heavy rainfall and flooding is likely to develop between Cooktown and Mackay as
Ex-Tropical Cyclone Olga and an associated monsoon trough moves ashore early
Monday. Flood warnings and a separate Severe Weather Warning are current for
these developing conditions.

People between Karumba in the southern Gulf of Carpentaria and Borroloola in the
Northern Territory should consider what action they will need to take if the
cyclone threat increases. If you are unsure about the actions to be taken,
information is available from your local government or local State Emergency
Service.

Details of Ex-Tropical Cyclone Olga at 10:00 pm EST [9:30 pm CST]:

REMARKS:
241500Z POSITION NEAR 16.3S 145.6E.
TROPICAL CYCLONE (TC) 09P (OLGA), LOCATED APPROXIMATELY 40 NM NORTH
OF CAIRNS, AUSTRALIA, HAS TRACKED WEST-SOUTHWESTWARD AT 04
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED IMAGERY SHOWS A
SIGNIFICANT DECREASE IN CONVECTION OVER THE PAST TWELVE HOURS AND
SURFACE OBSERVATIONS THROUGHOUT THE AREA HAVE CONSISTENTLY BEEN LESS
THAN GALE-FORCE STRENGTH. THEREFORE, THE CURRENT INTENSITY OF 35 KTS
IS SUPPORTED BY THE PGTW DVORAK ESTIMATE AND JUSTIFIED DESPITE THE
APPEARANCE OF AN EYE-LIKE FEATURE IN A 240411Z AMSR-E MICROWAVE
IMAGE. AS FOR POSITION, THE CAIRNS RADAR SHOWS A BROADENING LOW
LEVEL CIRCULATION CENTER (LLCC) AND THE CURRENT SYSTEM POSITION IS
HIGHLY UNCERTAIN DUE TO THE LACK OF CONVECTION IN THE RADAR
SIGNATURE AND CLOUDS OBSCURING THE LLCC IN THE INFRARED IMAGERY.
ADDITIONALLY, RECENT OBSERVATIONS SUGGEST THAT TC 09P MAY EVEN BE
DRIFTING SLOWLY SOUTHEASTWARD AS IT IS CURRENTLY LOCATED IN AN
OPPOSING STEERING ENVIRONMENT. SINCE THE SYSTEM HAS WEAKENED, THE
STEERING LEVEL HAS SHIFTED TO THE LOWER LEVELS WITH THE CROSS-
EQUATORIAL WESTERLY FLOW TO THE NORTH BECOMING MORE OF A STEERING
INFLUENCE THAN THE MID-LEVEL SUBTROPICAL RIDGE TO THE SOUTH. OVER
THE NEXT 12 HOURS, TC OLGA IS EXPECTED TO RESUME A SLOW, WESTWARD
TRACK AND DISSIPATE AS A SIGNIFICANT TROPICAL CYCLONE OVER THE NEXT
24 HOURS. NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT WITH A
WESTWARD TRACK. HOWEVER, IT APPEARS THAT THE MODELS ARE OVER-
INITIALIZING THE INTENSITY OF THE SYSTEM AND ARE SUBSEQUENTLY MOVING
OLGA FASTER THAN THE CURRENT FORECAST VIA THE SUBTROPICAL RIDGE.
FINALLY, THE POSSIBILITY REMAINS THAT TC O9P MAY RE-INTENSIFY TO
MINIMAL GALE STRENGTH IN THE GULF OF CARPENTENTARIA AROUND TAU 48.
THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON
WARNING CENTER (NAVMARFCSTCEN). THE SYSTEM WILL BE CLOSELY MONITORED
FOR SIGNS OF REGENERATION. MAXIMUM SIGNIFICANT WAVE HEIGHT AT
241200Z IS 10 FEET.

REMARKS:
Ex-TC Olga has been relocated based on radar and surface observations closer to
the SE Gulf of Carpentaria coast near Burketown. A small convective cluster is
evident near this LLCC, and large areas of deep convection persist over Gulf
waters to the north, associated with a broad mid-level circulation. The system
is forecast to move WNW parallel to the southern Gulf coast under the influence
of the mid-level ridge to the south, then recurve towards the N or NE late
Wednesday or Thursday as an upper trough approachs from the west. The
broad-scale environment is favourable for redevelopment of a tropical cyclone,
if the LLCC moves over southern Gulf waters, with divergent outflow aloft and
strong monsoonal westerlies to the north.

What is that map saying? They expect it to be a 1 over land and a 2 over water? Is that the Saffir Simpson scale? I thought I understood these maps but now I'm not so sure.
