The interactive map shows both Center Weather Advisories (CWAs) and
Meteorological Impact Statements (MISs). The CWAs show up as polygons
for the hazard area. The outlines of the polygons are black to make them
distinctive from SIGMETs. The polygons are filled based on hazard type
(See Fig. 1).
Figure 1: CWA polygon colors
MIS are display as yellow circles in the middle of the ARTCC region. Only
regions with a valid MIS are shown.
Figure 2: MIS symbol
Each polygon or circle is clickable to obtain the text of the advisory
or statement.

type of basemap. The default is light.
sat={on|off} - This turns the satellite layer on or off. The
default is off.
satprod={ir|vis|wv} - Specifies the type of satellite image. The
default is ir.
satopacity=# - Specifies the satellite image opacity
(0=transparent to 1=opaque). The default is .5.
satlabform={on|simple|off} - Specifies the satellite label format.
The choices are "on" which shows type of image and time, "simple" which
shows only image type and "off" which shows no label. The default is
"full".
rad={on|off} - This turns the radar layer on or off. The default
is off.
radprod={rala|cref} - Specifies the type of radar image: "rala" for
reflectivity at lowest altitude or "cref" for composite reflectivity. The
default is rala.

(0=transparent to 1=opaque). The default is .75.
radlabform={on|full|simple|off} - Specifies the radar label format. The choices
are "on" or "full" which shows type of radar and time, "simple" which shows only
radar type and "off" which shows no label. The default is "full".

pcpn - precipitation
cwaopacity=# - Specifies the CWA polygon opacity
(0=transparent to 1=opaque). The default is .75.
mis={on|off} - This turns the MIS layer on or off. The
default is on.
