This study investigates situational preparedness dynamics for six sequential TC events that affected seven states in the United States from 2020 to 2024. We find a combined effect of forecast wind speed and landfall sequence of a TC. Stronger forecast wind is always associated with higher preparedness levels. People tend to show a higher preparedness level for the second TC but are more sensitive to the increasing forecast wind speed of the ","authors_text":"Dazhi Xi, Fengxiu Zhang, Ning Lin, Qingchun Li, Tianle Duan","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.soc-ph","submitted_at":"2025-04-23T16:54:22Z","title":"Situational Preparedness Dynamics for Sequential Tropical Cyclone Hazards"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2504.16878","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:55dc855da5d65670b34f70f22decb6178c5e8959f37983128f04d597e013ecc5","target":"record","created_at":"2026-07-05T10:53:05Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"3aa494d8a9ba3cb156cb51f29908f486aa38a428e566badf6d78215d8912f6be","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.soc-ph","submitted_at":"2025-04-23T16:54:22Z","title_canon_sha256":"ffbad7b9bb176d5411cc6a230d8ec51b33152f9c9f6cd40f0e8070de0726fb24"},"schema_version":"1.0","source":{"id":"2504.16878","kind":"arxiv","version":1}},"canonical_sha256":"002859a16b48c733a76dbda601201ba4331c649d67fa9c8debc2fb9858657ce1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"002859a16b48c733a76dbda601201ba4331c649d67fa9c8debc2fb9858657ce1","first_computed_at":"2026-07-05T10:53:05.763061Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:53:05.763061Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BYHeI8sJkIBR1LaVLxMuTvqMpSLVYetk/T2fG5YHVQAJyuywJprgP1Wk//8C5c7E70tRL25wxe4IeHjQmbOgAg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:53:05.763604Z","signed_message":"canonical_sha256_bytes"},"source_id":"2504.16878","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:55dc855da5d65670b34f70f22decb6178c5e8959f37983128f04d597e013ecc5","sha256:7148d888586add70b39824b96741f5dfb315b0ecbb83880d762ce0cc5b39d7e1"],"state_sha256":"e43e86b3e05686543144a747615e2ca97fce92f14c173738b2ffdcae1fd0d2bc"}
