Explosive Cyclogenesis Hits British Columbia

What is Explosive Cyclogenesis?

Explosive cyclogenesis is a meteorological phenomenon that refers to a rapid intensification of a low-pressure system. It occurs when the atmospheric pressure at the center of the low drops by at least 24 millibars (0.71 inches of mercury) within 24 hours.

Cyclone Hits British Columbia

On November 26, 2021, an explosive cyclogenesis event occurred off the coast of British Columbia, Canada. The low-pressure system rapidly intensified, reaching a minimum central pressure of 942 millibars (27.82 inches of mercury) by November 27.

The cyclone brought strong winds, heavy rain, and flooding to coastal British Columbia. Wind gusts of up to 140 kilometers per hour (87 miles per hour) were recorded, and some areas received more than 200 millimeters (7.9 inches) of rain.

Impacts of the Cyclone

The cyclone caused widespread damage to infrastructure and property in coastal British Columbia. Roads were closed, power lines were downed, and buildings were damaged. The flooding also led to evacuations and landslides.

The cyclone also had a significant impact on the environment. The strong winds and waves caused erosion along the coast, and the heavy rain led to flooding in rivers and streams.

Environment and Climate Change Canada

Environment and Climate Change Canada (ECCC) is the federal department responsible for weather forecasting and monitoring in Canada. ECCC issued several weather warnings in advance of the cyclone, and they continue to monitor the situation.

ECCC is also working with other government agencies to assess the damage caused by the cyclone and to provide assistance to affected communities.

Conclusion

The explosive cyclogenesis event that hit British Columbia was a powerful and destructive storm. It caused widespread damage and flooding, and it had a significant impact on the environment. ECCC continues to monitor the situation and provide assistance to affected communities.
