Blue, highlighted areas (NOTAM's)

Hello, I just noticed that a blue area has been highlighted around Mexico. What does this mean? Also I see there are red areas as well. When I click it a whole bunch of text shows up. What does this text mean, i guess the question is, how do I read NOTAM Reports?

 

WVMX31 MMEX 050243 MMEX SIGMET 1 VALID 050237/050837 MMMX- MMEX MEXICO FIR/UIR/SRR VA POPOCATEPETL 01901.2N 09837.2W OBS AT 050237Z VA CLD EXTD 10NM FM SUMMIT BWTN SFC /FL220 MOV SE AT 20KT WKN. OUTLK AT 050830 UTC VA CLD DISSIPATED.=

 

 

Thanks!

It's a sigmet

Hi Vlad,

 

You clicked on a SIGMET. Sigmets are one of the default layers, you can change your settings by clicking on the "Layers" link in the upper right.

 

Sigmets are notams dealing with meteorological events affecting all aircraft. 

 

In this case the reported phenomenon is "VA" or Volcanic Ash. This sigmet is reporting that a Volcanic Ash cloud extending 10 nautical miles from the summit of Popocapetl (19 degrees 1.2 minutes North latitude, 98 degrees 37.2 minutes West Longitude) was observed at 02:37 Zulu on February 5th between the surface and Flight Level 220 moving Southeast at 20 knots, weakening. Additionally, the sigmets predicts (outlook) that at 08:30 Zulu on February 5th the Volcanic Ash Cloud will have dissipated.

 

For more information on how to read sigmets, see:
