The Braer Storm of January 1993 was the most intense extratropical cyclone on record for the northern Atlantic ocean. Developing as a weak frontal wave on January 8, 1993, the system moved rapidly northeast. The combination of the absorption of a second low-pressure area to its southeast, a stronger than normal sea surface temperature differential along its path, and the presence of a strong jet stream aloft led to a rapid strengthening of the storm, with its central pressure falling to an estimated 914 hPa (914 mb; 27.0 inHg) on January 10. Its strength was well predicted by forecasters in the United Kingdom, and warnings were issued before the low initially developed.
