Emergency Frequencies to Avoid

CQ Contesting Editor Dave Siddall, K3ZJ, shares the following, courtesy of the IARU Region 1 website, and encourages contesters and other hams to avoid frequencies being used for hurricane- and earthquake-related nets. Remember - stations may be able to hear you even if you cannot hear them. These frequencies are in addition to the Hurricane Watch Net's frequencies of 14.325 and 7.268 MHz:

To amplify Ward N0AX's suggestion:  all contesters WORLDWIDE this weekend -- especially those competing in the WAEDC and NA SPRINT contests, please avoid the multiple emergency frequencies being used in the Caribbean and United States (IARU Region 2) for emergency and related hurricane communications and give them wide berth.  CW and digital stations should keep 4 kHz away (at least) on the correct side (low for LSB nets, high for USB nets) of the SSB nets operating in the Caribbean to avoid interfering with their communications.

The best link to keep up-to-date appears to be that of IARU Reg. 1. To keep up-to-date, check:
(I did not find any up-to-date info on the IARU Region 2 website.)

The National Emergency Network of the Mexican National Society (FMRE) declared on 8th September that it would be using the following frequencies as they prepared for the arrival of Hurricane Katia.
With the magnitude 8.1 earthquake hitting Mexico at 0449UTC today, assume that these frequencies are in use now as they respond to that disaster.
20m 14,120 kHz
40m 7,060 kHz
80m 3,690 kHz
14325 kHz was also expected to be used to co-ordinate with the USA Hurricane Watch Net.
Various Winlink nodes may also be used to deal with the emergencies.
With HF propagation disturbed after the X9 solar flare on Wednesday, please take all steps to avoid interference to emergency communications activities in the Caribbean.
