Rain set in along the eastern seaboard on Monday, marking the beginning of a soggy week for our most heavily populated stretch of coastline. By 3pm, Lismore had already received nearly 100mm of rain, their heaviest fall in three years. This prompted a flood watch for coastal rivers from the Queensland border to the Nambucca Valley. Away from the northeast corner of NSW the rain was patchy on Monday but will become heavier and more widespread on Tuesday as a trough of low pressure deepens just off the coast. 24 hour totals should easily exceed 50mm from about Brisbane to Taree on Tuesday, while showers in some form extend from the Sunshine Coast to the Victorian border. Heavy rain should continue on Wednesday and Thursday in southeast Queensland but should ease to showers along the NSW coast. By Friday only isolated showers will remain but cumulative totals through the week could easily reach 100mm or more from Brisbane to about Newcastle with totals possibly even climbing over 200mm in the Northern Rivers and Mid North Coast districts of NSW.
