International SIGMETs - SIGMETs issued outside the CONUS.
CWAs - Center Weather Advisories issued by the CWSUs.
Each type of hazard is colored differently. The convective SIGMETs are
filled red. The turbulence SIGMETs are brown. The icing SIGMETs are blue.
Ash SIGMETs are gray. All SIGMETs have a red border.
Figure 1: SIGMET polygon colors
CWAs have the same fill color but the outlines and text are black rather
than red so they can be distinguished from SIGMETs.
Figure 2: CWA polygon colors
SIGMETs can be filtered by altitude range by adjusting the Top and Bottom
selectors.
The SIGMETs and CWAs are all clickable to access the raw text of the
product.
NOTE: Because of differences in encoding, the international SIGMETs
only show the region or FIR that the SIGMET is valid. In some cases, a polygon
can be decoded and resulting area shown. In most others, the SIGMET is only
valid for a subset of the region shown. Multiple SIGMETs may be valid for
the same area. PLEASE refer to the SIGMET text or go to the SIGMET data page
to get all the SIGMETs in an area.
URL Options
Here is a list of the URL options:
date=yyyymmddhhnn - This selects a specific date and time
to display.
time=hr - This selects the initial time on the time slider
(def: 0).
timelabform={full|simple} - This selects time slider labels. Full
shows -/+ hours from current. Simple shows just the time and "Forecast for"
if it's a future time.
refresh=min - This sets the auto-refresh time interval
(def: 5 min).
tz=tz - This sets the time zone to show in the date header.
This can be "local" which is the browser time zone or "label,offset" which
is the zone name and offset in hours. For example "CDT,-5". (def: UTC).
region=reg - This will center the map to a specific region.
Options include: "conus", "us", "northeast", "ne", "southeast", "se",
"northcentral", "nc", "southcentral", "sc", "northwest", "nw",

"zoa", "zob", "zse", "ztl" (def: none).
center=lat,lon - This will center the map at a specific
latitude and longitude. The default is 39,-97.
zoom=level - This sets the zoom level. The default is 4.
A higher number zooms in. A lower number zooms out.
fullmode=(screen|window) - This sets the full screen mode. "screen"
sets it to full screen. "window" sets it to fill the current browser window. The
default is screen.
fullscreen=(on|off) - This sets the display to go into full window
if fullmode=window.
basemap=(light|dark|simple) - This selects the
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.
radopacity=# - Specifies the radar image opacity
(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".
sigmet={on|off} - This turns the SIGMET layer on or off. The
default is on.
sigtype=param - Specifies the types of SIGMETs to display.
The default is all. The types are:
trop - tropical cyclone
conv - convective
turb - turbulence
ice - icing
ifr - IFR
va - volcanic ash
sigopacity=# - Specifies the SIGMET polygon opacity
(0=transparent to 1=opaque). The default is .75.
sigheight={on|off} - This turns the SIGMET height labels on or
off. The default is off.
cwa={on|off} - This turns the CWA layer on or off. The
default is on.
cwatype=param - Specifies the types of CWAs to display.
The default is all. The types are:
conv - convective
turb - turbulence
ice - icing
ifr - IFR
pcpn - precipitation
cwaopacity=# - Specifies the CWA polygon opacity
(0=transparent to 1=opaque). The default is .75.
highways={on|off} - Turns highway layer on or off. These are
primarily interstates. The default is off.
jetroutes={on|off} - Turns the jetroutes layer on or off. The
default is off.
firs={on|off} - Turns the ARTCC/FIR layer on or off. The default
is off.
navaids={on|off} - Turns the Nav Aids layer on or off. The
default is off.

The default is 1.
navlabel={on|off} - Turns the Nav Aid labels on or off. The
default is off.
metric={on|off} - Specifies to display data in metric units. The
default is off.
