We used synthetic absorption spectra to identify and characterise coronal broad Ly$\\alpha$ absorbers (CBLAs), which represent H I absorption features produced by the warm-hot CGM at temperatures above $10^5$ K. Our study implies that CBLAs have a significant absorption cross-section, $f_c$, around MW-like galaxies.
