4.8.12  Cell Movement
Cell  Movement  data  shows  the  location  and  movement  of  storm  cells  as 
identified  by  a  ground-based  system.  Cells  are  represented  by  yellow  squares, 
with direction of movement indicated with short, orange arrows. 
Figure 4-35  XM Weather - Cell Movement
On most applicable maps, Cell Movement data is selected for display along 
with  NEXRAD.  On  the  Weather  Data  Link  Page,  Cell  Movement  data  can  be 
selected independently.

4.8.13  SIGMETs and AIRMETs
SIGMETs    (SIGnificant  METeorological  Information)  and  AIRMETs 
(AIRmen’s METeorological Information) are broadcast for potentially hazardous 
weather  considered  of  importance  to  aircraft.  A  Convective  SIGMET  is  issued 
for hazardous convective weather. A localized SIGMET is a significant weather 
condition occurring at a localized geographical position. 
When enabled, SIGMET/AIRMETs advise the pilot of potentially hazardous 
weather  to  all  aircraft.  SIGMET/AIRMET  data  covers  icing,  turbulence,  dust, 
and volcanic ash as issued by the National Weather Service. The update rate is 
every 12 minutes. 
Figure 4-37  XM Weather - AIRMETs
When enabled, the following AIRMETs are available for display: 
•	 Icing
•	 Turbulence
•	 IFR conditions
•	 Mountain obscuration
•	 Surface winds

4.8.14  METARs
 NOTE:  Atmospheric pressure reported for METARs is given in hectopascals 
(hPa), except in the United States, where it is reported in inches of mercury (in Hg). Temperatures are reported in Celsius. 
 NOTE:  METAR information is only displayed within the installed aviation database service area. 
METAR (METeorological Aerodrome Report), known as an Aviation Routine 
Weather  Report,  is  the  standard  format  for  current  weather  observations. 
METARs  are  updated  hourly  and  are  considered  current.  METARs  typically 
contain  information  about  the  temperature,  dew  point,  wind,  precipitation, 
cloud  cover,  cloud  heights,  visibility,  and  barometric  pressure.  They  can  also 
contain information on precipitation amounts, lightning, and other critical data. 
METARs are shown as colored flags at airports that provide them.

4.8.15  Surface Analysis and City Forecast
 NOTE:  Surface Analysis and City Forecast data are displayed only within 
the installed Aviation Database service area. 
Surface  Analysis  and  City  Forecast  information  is  available  for  current  and 
forecast  weather  conditions.  Forecasts  are  available  for  intervals  of  12,  24,  36, 
and 48 hours by pressing the  SRFC TIME soft key or in the Page Menu Weather 
Setup options.  When enabled, the Surface Analysis forecast shows frontal lines indicat-
ing weather fronts and the direction they are moving. High and Low pressure 
centers are noted with a large H or L. The Forecast Time menu item will step 
through the intervals manually.

A Cold Front is a front where cold air replaces warm air. A blue line with 
blue triangles that point in the direction of the cold air flow. 
Figure 4-42  XM Weather - Cold Front
A Warm Front is where warm air replaces cold air. An orange line with 
orange half moons that point in the direction of the warm air flow.

A Stationary Front is a front with very little horizontal movement. The line 
alternates with orange and blue sections which point in opposite directions to 
symbolize little movement. 
Figure 4-44  XM Weather - Stationary Front
An Occluded Front is where a cold front has overtaken and merged with a 
warm front. The line alternates with the blue triangle and orange half moon sym-
bols on the same side of the line pointing in the direction the front is moving.
