1920 Eastern Island Tornado Outbreak

The 1920 Eastern Island Tornado Outbreak was the first recorded by the SWWS. It was by no means the worst, however.

Meteorogical History
A cluster of storms formed over the water in the Eastern Island Channel between the main landmass and the Eastern Island province. The EIWS placed the island under an enhanced (Level 3 of 5) risk for severe weather. As the system intensified, the EIWS upped it to moderate (Level 4 of 5) and placed the entire Eastern Island world province under a Tornado Watch. The cluster impacted the region and dropped several tornadoes.

Pre-Impact Report after Moderate Threat is put in place (EIWS)
An intense cluster of storms is set to impact Eastern Island later in the day. We are expecting rapid development of severe storm cells, some becoming supercells. Tornadoes are likely. Be advised that this is a dangerous situation. Take shelter if you feel unsafe during severe weather or when a warning is issued

Post-Impact Report (EIWS)
A powerful cluster of supercell thunderstorms rolled through the area Friday afternoon and evening. There were several reports of wind damage, and at least 18 tornadoes have been reported, causing a large amount of damage.
