Abstract
The commonly used approach to predict and evaluate the wind risk in Peninsular Malaysia is to employ the basic wind speed (Vs) hazard map, which underestimates the real damage due to the limitation of factors considered by the current map. This paper aimed to develop a new wind hazard map for Peninsular Malaysia based on the site wind speed (Vsite) rather than the Vs using the Geographical Information System. The development of the Vsite map considered the effects of the Land Use Land Cover (LULC) and the topography conditions that were not taken into consideration by the Malaysian Standard during the development of the Vs map. The statistical analysis proved that the wind hazard in Peninsular Malaysia is directly proportional to the LULC and inversely proportional to the Hill Shape Multiplier. In addition, the results showed that the existing Vs map underrated the wind hazard in Peninsular Malaysia by almost 9.02% to 17.79% compared to the developed Vsite map. Therefore, the use of the newly developed map to evaluate the wind hazards will significantly enhance the assessment, and the new map has the potential to be incorporated into the Malaysian Standard for this purpose.

Wind may cause severe damage to property, loss of life, and other catastrophic events
This study aimed to construct a wind hazard map for areas of Peninsular Malaysia that are not considered as a reference in the MS1553:2002 [10] by considering the Vsite data
General form of finding an interpolated value at a given point using Inverse Distance Weighting (IDW) is presented in Equation (2): of this study, Peninsular Malaysia was divided into four regions: Ps
Summary
Wind may cause severe damage to property, loss of life, and other catastrophic events. Malaysia is an Asian country located near the equator and is well-known for its rainforests This makes it extremely important to investigate its wind flow pattern, which is mainly controlled by two major monsoon periods, namely the northeast monsoon (November to March) and the southwest monsoon (May to September) [4]. A specific period between the two major monsoons (April and October) is called the intermonsoon, in which frequent thunderstorm events occur, causing stronger and gustier windstorms than those of the northeast and southwest monsoons. These windstorms are classified within the meteorological disaster subgroup [5]
