Global Disaster Alert and Coordination System issued an orange alert for a tropical cyclone affecting México, SIMON-26
The Global Disaster Alert and Coordination System (GDACS) has an orange alert in force for a tropical cyclone affecting México, SIMON-26. GDACS records the event as beginning on 7 October 2026, and has assessed it as far as 16 October 2026. The event is listed as still current, so that second date is how far the assessment reaches, not the date the hazard ended.
GDACS gives the maximum wind speed as 250 km/h. That is the figure in the record and nothing has been derived from it.
GDACS assembled this alert from the United States National Oceanic and Atmospheric Administration. An alert level is GDACS's own estimate of the humanitarian impact a hazard of this size is likely to have, calculated automatically from the hazard's measured extent and the population and vulnerability of the area. It is not a count of people affected, injured or killed, and this brief does not report any such count.
GDACS states that its information is indicative, that it should not be used for decision-making without other sources, and that it does not replace or override any warning issued by a national or local authority. Alert levels are revised as an event develops; any change to this record is shown in the revision history on this page.

GDACS records the event as beginning on 7 October 2026, and has assessed it as far as 8 October 2026. The event is listed as still current, so that second date is how far the assessment reaches, not the date the hazard ended.
GDACS gives the maximum wind speed as 203.7 km/h. That is the figure in the record and nothing has been derived from it.
GDACS assembled this alert from the United States National Oceanic and Atmospheric Administration. An alert level is GDACS's own estimate of the humanitarian impact a hazard of this size is likely to have, calculated automatically from the hazard's measured extent and the population and vulnerability of the area. It is not a count of people affected, injured or killed, and this brief does not report any such count.
GDACS states that its information is indicative, that it should not be used for decision-making without other sources, and that it does not replace or override any warning issued by a national or local authority. Alert levels are revised as an event develops; any change to this record is shown in the revision history on this page.
