A parametric study has been carried out to elucidate the characteristics of flow past a square cylinder inclined with respect to the main flow for Re$\leq$150. Reynolds number and angle of incidence are the key parameters which determine the flow characteristics. This study would be the first step towards understanding flow pattern past a cylindrical structure under a strong gust of wind from the viewpoint of wind hazards. A complete classification of flow pattern has been obtained in the laminar region.
