FORECASTS:

The section required is the "District Forecasts - Central, Western, Southern" section.

FORECAST CHARTS:

Note: Latest Analysis Chart is derived from actual data and the time of compilation is based on Eastern Standard Time, therefore, deduct 2 hours from the 'valid from' time. eg valid time is 10.00am, therefore Western Australian Time is 8.00am

MSLP= Mean Sea Level Pressure, showing isobars of equal barometric pressure at ground or sea level. Wind direction for high pressure systems travel anti-clockwise and Low Pressure systems clockwise. (The opposite prevails in the northern hemisphere)

Where data shows "Valid at 00.00 UTC" then add 8 hours to the time for Western Australia ie 00.00 UTC + 8hrs = 8.00am the next day as Western Standard Time and correspondingly "Valid at 12.00 UTC" represents 8.00pm and as 12.00 UTC is always given as a next day forecast, it becomes 8.00pm the following day.

The 4 day Forecast Chart: colour, black & white section is also a very handy and accurate tool for assessing the weather conditions mid-week for the weekend and for preparing and selecting the birds accordingly.

SATELLITE IMAGES:

For satellite images, remember to add 8 hours to the time shown for the photo, also Infrared is the better and more frequent image - infrared also measures temperature and the whiter the formations the colder the air mass and indication of severity of weather and rain bearing frontal systems.

RADAR IMAGES:
(footprint Perth - Learmonth)

PERTH (128 km radius)

GERALDTON (128 km radius)

CARNARVON (128 km radius)

LEARMONTH (128 km radius)

Perth and Learmonth radars are produced in real time (within 10 mins) and will update automatically or alternatively the refresh button can be used. Geraldton and Carnarvon radars are shared and updates are often of longer duration. The time and day is shown at the foot of the picture under the heading of WST. Intensity of the rain can be judged by the Rain Rate scale in mm/hr at the bottom of the frame.
