ALERT™ subscribers can download similar stochastic event (SSE) IDs for Idalia from the Downloads tab of this posting on the ALERT website. Compatible with Touchstone® and Touchstone Re™, the SSEs were selected based on Idalia’s projected key meteorological parameters at landfall, in particular central pressure, storm track, and forward speed. They are recommended for use with exposures in Florida.
Catalog Viewer users are suggested to use the following initial ranges for search, in addition to the forecast track: Forward Speed 10-25 mph; Central Pressure 945 to 967 mb; Radius of Maximum Winds 25-37 mi.
Idalia is forecast to be a Saffir-Simpson Category 3 hurricane at landfall. A Hurricane Warning is currently in effect from the middle of Longboat Key northward to Indian Pass, including Tampa Bay. A Storm Surge Warning is in place from Englewood to Indian Pass. Peak surge of 8 to 12 feet is expected somewhere between Aucilla River and Chassahowitzka.
The Verisk ALERT team will release an updated set of similar stochastic events on Wednesday, August 30 by around 10:00 am Boston time. Additional plans beyond landfall - including an industry loss estimate - are very likely given the forecast, with timing and details still to be determined. Our next update will be Wednesday morning.
