Relief in sight after coast areas cop a drenching

The Gold Coast has been drenched with the heaviest day of rain since 2005 and parts of Brisbane have fared little better, Weatherzone reports.

Rainfall totals of 100-150mm were recorded along the coast from Brisbane's northeastern suburbs south to Tweed Heads over the past 24 hours.

The greater Brisbane area also recorded widespread totals of more than 50mm.

The heaviest rain in the past 24 hours fell on the Gold Coast where 183mm was recorded. This represented the largest 24 hour total for the region since June 2005, Weatherzone said.

It was also the wettest April day in the 17 years of records at the site. In just one half hour period, 34mm fell, creating enough run-off to cause flash flooding.

Brisbane recorded 76mm since yesterday morning with Brisbane Airport amassing 126mm - it's heaviest April day of rain since records began in 2001.

The city reached a top of just 19 degrees yesterday, its lowest maximum for this year.

Weatherzone said the heavy rain was triggered by a low pressure system that moved south along the Queensland coast overnight.

The low was able to produce so much rainfall for the southeast coast due to the warm ocean temperatures and easterly winds feeding large amounts of moisture into the low pressure system, Weatherzone said.

By this morning the low had moved offshore, allowing relief for drenched communities.

Weatherzone reports that during the next few days, the south-east coast should only experience a few showers due to moist southeasterly winds.

However on Thursday, more heavy rain may arrive as a trough is likely to deepen off the coast. This trough is unlikely to bring as much rain to the coast, with predictions of NSW receiving the bulk of the rainfall.
