Other areas in the Lower Hunter received some moderate falls, but were not
substantial as observed over the Raymond Terrace area. Newcastle University
recorded less then 50mm in the 48 hours till 9am today. Morpeth (Berry Park),
which is less then 10km from Raymond Terrace, recorded 90mm less then Raymond
Terrace (60mm in total) in the 48 hour time period ending 9am today. This shows
how localised the rainfall patterns were yesterday.
It is most likely that the downpour recorded yesterday in
Raymond Terrace was the heaviest in more then 25 years. back...
