NSW: Heavy rain, storms hit Central Coast
Sat 31 Aug 2019

On Friday 29 August an upper cold pool moved from inland NSW across the Hunter Valley and Mid North Coast. This created an offshore trough that swung moist southeasterlies and rain onto the Illawarra and Central Coasts. On the coastal side of the trough, convergence lines formed where winds from slightly different directions meet and, having nowhere else to go, have to rise producing rain. The instability caused by the cold upper temperatures made sure this rain was heavy.

With the system virtually stationary, some of these convergence lines sat over the same places for hours and, in the case of the Central Coast, for over a day before moving very slowly northwards. The Gosford area saw the heaviest falls. In the 2 days ended 09.00 today, Gosford AWS recorded 198mm, Kangy Angy to its north 200, and East Gosford 193, Ettalong 192 and Kincumber 181. The southern Newcastle suburb of Blacksmiths recorded 181 while Wyoming on the Lower Hawkesbury River had 184mm and Mangrove Mountain 168. Most gauges from the Hawkesbury to southern Lake Macquarie had over 150mm. Some areas had their heaviest two-day falls in over three years.

In Sydney, rain graded from heavy on the coast and North Shore to light in the west. Falls were generally between 50 and 80mm in the east and 20 to 50mm in the west. Highest falls in the 2 days to 09.00 today were 127mm at Wahroonga and Forestville and 117 at Hornsby and Mosman (Spit Bridge), much of it from one convergence line that lodged diagonally across the area. The Wollongong Coast saw falls mostly between 20 and 40mm, but the exposed Bellambi Point managed 77mm.

The upper cold pool caused a massive dump of hail in the Coffs Harbour area as it passed on Friday night. The storm was faithfully captured for Facebook in this video by Coffs Harbour Fishermans Co-op staff, picked up in this article by ABC News. Coffs Harbour gauges picked up 20 to 25mm while Sawtell, 8km to the south, recorded 37mm all in the space of less than an hour before 6pm.
