The country from which you are reporting. If your country does not appear
on the listing, send me email, and it will be added.
These fields are optional. If you provide them, your observations
will be plotted on maps containing the observations of
other users as well. Make sure the format is correct:
Example: New York City is latitude 40.77, longitude -73.98
Temperature, Dewpoint, and Relative Humidity:
If only two of the three are entered, the third is calculated.
Wind Direction, Speed, and Gust:
Enter the compass direction of the wind (ex: N,NNE,NE, etc), and the
sustained speed and maximum gust speed observed. You can also enter
VRB for wind direction to designate variable wind direction.
Enter the pressure reduced to sea level. While input in either inches of
mercury or millibars are accepted, output is only in millibars.
If you can see the sky and determine the approximate percentage of
cloud cover, choose either clear, Partly Cloudy, Mostly Cloudy, or Cloudy.
If you can not see the sky (because of fog, snow, etc), choose Obscured.
Otherwise, choose Don't Know. :)
Rain:Liquid precipitation, not freezing on the surface.
Snow:Any type of snow observed--snow flakes,pellets or grains.
Ice Pellets:Pellets of ice reaching the surface, excluding hail.
Ice Crystals:Flakes of ice resulting from extreme cold - usually below
Freezing Rain:Liquid precipitation which freezes on the surface.
Hail:Balls of ice falling to the ground as a result of convection
(thunderstorms). Different from ice pellets.
Thunder: Check if either thunder is heard or lightning is seen
within 5 miles. If the distance is greater, don't check this box, but just
make comments to it in the comments section.
Mist: Suspended water droplets in the atmosphere that do
not significantly reduce visibility.
Fog: Check if visibility is reduced significantly. If visibility
is known, enter in comments section.
Haze: Check if visibility is reduced significantly.
Smoke: Check if smoke is significantly reducing visibility.
Blowing Snow: Check if blowing snow is significantly
reducing visibility (causing drifting, driving problems, etc).
This is snow on the ground that is being picked up by the wind
into the air. Do NOT use this to report falling snow that is blowing
horizontally, or snow blowing off roofs.
Standard NWS guidelines state that BS should be reported only if the
wind speed is above 12mph. Reports of blowing snow will not be
accepted for wind speeds below this threshold.
Blowing Dust, Spray: Same as above, except for dust, spray
Basically, enter any obs-related specifics you'd like to add. These might include
rainfall totals, snowfall totals, snow depth, highs and lows, beginning or
ending times of precipitation, or damage reports. Do not clutter the
section with forecasts, conversation, or anything that can be left to
email or AOL Instant Messenger. Remember: this is a section for
*observations* that is used by others and the NWS. Use this space WISELY!
