The wind was fresh, and kept increasing until eleven o'clock, at which time it blew very hard; the rain fell in torrents, accompanied with loud claps of thunder and lightning, which at every instant imparted to one of the darkest nights the brightness of day. The course of the wind was from south-west to south, south-east, east, and north-east, where it blew hardest between one and three in the morning, giving me an apprehension that the house, pavilions, and all would be blown away together.

During these hurricanes in Mauritius, the wind usually makes
