All rights reserved.In the Lesser Antilles, coastal inundations and wave impact on infrastructure from hurricane-induced storm surges cause great threats to lives, properties, and ecosystems. One of the aims of this work is adaptation of data of estimating extreme surface wind speeds from satellite remote sensing for numerical modelling. In particular, we show that the Cyclone Global Navigation Satellite System (CYGNSS) mission of NASA, along with the Advanced Scatterometer (ASCAT), are able to capture a substantial part of the tropical cyclone structure, and to aid in determination of external force for storm waves in numerical model. For this work we use NAMI-DANCE (Yalciner et al 2014, Zaytsev and Pelinovsky 2011) numerical models and statistical methods to investigate worst case scenarios of storm surges levels for the case study of Martinique and Guadeloupe Islands.. Results confirm that direction of cyclone propagation plays a major role in Lesser Antilles. Assessing current and future storm surges hazard with sufficient spatial resolution is of primary interest to help coastal planners and decision makers to develop mitigation and adaptation measures.
