Parts of the Gold Coast and Northern Rivers have endured days of wet weather and will need to keep their gumboots handy, with more rain just around the corner. In the past three days there have been widespread falls of 50-100mm along the coastal stretch, thanks to a low pressure trough that has lingered offshore. Many parts have now seen well above their normal June rainfall. Coolangatta has had 121mm since last Thursday, pushing their monthly total to 225mm, nearly twice the normal amount. The Seaway has copped 80mm in recent days, while Burleigh Waters has had 76mm, bringing both of their running totals to 145mm. Just across the border, 66mm has landed in the gauge at Murwillumbah over the last three days, that's 157mm all up for the month. A low pressure system has now developed within the trough east of Fraser Island. The low is expected to deepen as it moves to the south, causing conditions to deteriorate along the coastal stretch. Monday is looking like the wettest and wildest day, with as much as 50-100mm possible along exposed coastal parts. Showers will extend as far south as the NSW Hunter coast, with the QLD and NSW border region a good chance to pick up the heaviest falls. It is likely to be the wettest start to July in many years for any places that do get this much. The low may also whip up gale-force winds and dangerous surf conditions, which will be bad news for the Goldy's already depleted beaches. The lack of sunshine will also lead to below average day-time temperatures, so locals will need to rug up when heading outdoors. The low will weaken and start to move further offshore by Tuesday, however showers will continue for a day or two before the sunshine returns later in the week.
