We are considering putting free wind information on the forecast pages. The MIST system we sell for aerodrome use, currently has colour state maps. We are planning to launch a new service later this year on the web, which will include this sort of service. These value-added products require development work and relatively large amounts of manpower to produce, therefore we will be unable to give these away free to the user. Many questions about hurricanes are answered on our Tropical Cyclones page.
Atmospheric pressure varies over time and space and also varies with height.
This is done so that readings from different locations can be compared, with differences due to height being removed. Go to the Met Office's observation page and choose the station nearest to your location - on a quiet weather day the distance away from you will not be significant. Adjust the barometer to the station's pressure value. You can check your barometer on other days but will have to compensate for fast-changing pressures or distance if the pressure is low or changing fast. The observation includes information about how the pressure is changing.
