Short summary

We quantified the impact of hurricanes Irma and Maria on the PTWC initial tsunami warning capability for the Caribbean region after accounting for hurricane-related seismic station outages. Within the eastern Caribbean region the hurricanes exacerbated outages to an astonishing 82 % of the available 76 stations. This resulted in up to 02:33 and 04:33 min added to the earthquake detection and response times, effectively knocking out PTWC's local tsunami warning capabilities in the region.
