area of low pressure that developed into Tropical Cyclone Graham on 27 February. The storm moved slowly to the east-southeast, and after turning to the south it peaked as a tropical storm and made landfall on Western Australia

Meteorological history
On 23 February 2003, an area of
maximum sustained winds. The first warning was issued on Graham later that day.[2]
Initially exhibiting characteristics of a
ridge to the south of Graham caused strong westerly winds that moved the storm slowly east-southeastward. However, a deep trough eroded the ridge, allowing the cyclone to move more towards the south.[1] According to the JTWC, the storm had intensified late on 28 February, though at the same time the BoM noted the slight weakening of the storm.[2] Graham reached its peak intensity that day while nearing the coast.[1]
The storm made landfall at Western Australia's Eighty Mile Beach at 1400 UTC on 28 February, and began to weaken. The storm had dissipated on 1 March; the BoM issued their last advisory on the cyclone at 0400 UTC that day, while similarly, the JTWC issued their last advisory just two hours later.[2] The storm's remnants died out in the country's desert.[3]
Impact
In advance of the cyclone, the communities of Wallal,
flooding and road closures, and swelled a river passing through Fitzroy Crossing, though the river only topped its banks slightly.[5] Near that town, at Blue Bush Creek, while a group of people attempted to cross floodwaters, two men were swept away. Both men were rescued, though one died before emergency services arrived.[6] In addition to the flooding, a number of trees were downed.[7]
No significant damages were reported.
Following the storm, the name Graham was
retired from the Australian region basin.[8]
