Parts of southern and central NSW are seeing the heaviest rain in almost a year and with this rain heading east on Thursday, Warragamba Dam continues to release its catchment as dam levels remain high. West Wyalong in the Central West Slopes and Plains recorded 13mm of rain between 9am and midday today. While this is well short of the 53mm it usually sees during February, this short burst of rain is the heaviest four months. Cabrammura received 44mm during the 24 hours to 9am this morning, the heaviest since March, while in the South West Slopes, Mundarlo recorded 51mm. The wet conditions will not hang around the state's south for long as the low pressure trough responsible for the rain begins to move north and east. Thursday will see widespread falls of 20-40mm from central to eastern parts of the state. The heaviest falls will be in the central west, although eastern districts as far north as Sydney should see some rain. Recent rainfall in the Sydney region caused the Warragamba Dam to spill over. Last weekend, Badgery's Creek received a total of 95mm and while the last few days have seen some relief, the upcoming showers have prompted a flood watch. Renewed river rise and some minor to moderate flooding is expected from Thursday night onwards in the Hawkesbury and Napean rivers. Then from Friday morning, Wollombi Brook in the Hunter Valley should experience moderate flooding
