Current Weather
and Forecasts: The
current weather data is gathered by a network of weather stations; the
forecasts are produced by various governmental and private
organizations.

are similar to infrared, but they are able to show the specific "energy
signature" emitted by water vapor. Dry air shows up as dark areas,
while moist air shows up as light areas.

Radar/Precipitation: These images are generated by ground-based Doppler radar stations
located around the country (see map here). Many
different types of images can be produced from radar data, and most have
to do with amount and type of precipitation. Radar is explained in more
detail here. |

| Active Tropical
Cyclones/Hurricanes: Tropical
cyclones are storms which form over warm, low-latitude ocean waters.
In the Atlantic and Eastern Pacific Oceans they "achieve" hurricane status
once the sustained winds reach 72 mph or higher. See the Saffir-Simpson
Scale for more information on rating the severity of tropical
cyclones. For information and history on the naming of storms, click

Sacramento Area River Levels and Flood
Warnings: Here you will find reports on exactly how much
water is running in Sacramento Area streams and rivers. Discharge
(or streamflow) is a measure of the amount of water flowing in the stream
(measured in cubic feet per second). One cubic foot is about the volume of
a basketball. River stage is basically the elevation of the water
level in the river. These reports will indicate whether the stream
or river is at or above flood stage.
