A significant rainfall event is expected to develop over eastern NSW during the 14th to 15th October 2014 in response to rapid cooling in the upper atmosphere and onshore winds in the southern part of the low. Rain fall totals may exceed 100mm in regions along the Hunter Coast with pockets of 150mm being predicted. The Hunter region had received very little rain during the past month or so so this would be a case of too much rain too soon and probably will lead to flooding along the coastal parts.
Update: An intense east coast low complete with couplets on doppler radar. Very strong winds were reported from near Wattamolla to Kurnell with winds of the order of 130km/h in one observation! 161km/h from the south! The circulation passed near the Sydney Airport with very heavy rain accompanying the winds as well as cloud to ground lightning! In the Blue Mountains, snow and ice has caused the closure of both the Great Western highway and Bells Line of Road! Temperatures were hovering near and below 0.5C with precipitin most likely snow!
