Weather Situation
A high pressure system passes to the south of Tasmania between Tuesday and Thursday, as a broad low pressure system moves slowly over the southeastern mainland. Together they direct a moist easterly airstream over Tasmania through the middle of the week that is expected to bring widespread rain to the east and southeast. A cold front will then slowly approach from the west during Friday.
