| Extreme Rainfall | |||||||||
| ~ For the second time in under 12 months flood warnings were issued for rivers around the Hunter. Consistent rains | |||||||||
| during summer along with two particularly heavy rainfall days this month culminated in minor to moderate flooding | |||||||||
| particularly along the Williams River. I recorded 62.0mm till 0900 on the 23rd which consisted of only light to moderate | |||||||||
| but steady rain. The 25th however saw 84.0mm till 0900 with light rain punctuated by some very heavy showers. | |||||||||
| One in particular at 0419 produced a max rain rate of 180mm/hr which is a record since the new gauge was bought | |||||||||
| into use from 1 Jan - note this surpassed that of any storms we received thru the whole of summer.. | |||||||||
| Rainfall Rate Calculations - for new TB3 gauge | |||||||||
| ~ As mentioned in my Oct 2007 report, I am still getting an erratic tipping pattern. I have since obtained data from my | |||||||||
| mate's gauge (same sort as mine) for similar results. I contacted Hydrological services regarding this but they have | |||||||||
| apparently never heard of this. As a result I have adapted my rain rate calculations to be taken over 1mm at a time - that | |||||||||
| is the time taken for each block of 5 tips to occurr. | |||||||||

| ~ Fri 25th - Made another trip to Hunter Springs to gather data & install a new wireless thermometer for Mrs Wright. | |||||||||
| With this she will now be able to read the temperatures from inside the comfort of her home to a resolution of 0.1°C. | |||||||||
