The Moon normally rises in the east and sets in the west due to Earth's rotation. However, variations in the Moon's rising direction can occur based on the Moon's phase, the time of year, and observer location. For example, around the full moon phase, the Moon rises close to due east and sets close to due west, often opposite the setting Sun. Sometimes, the Moon may appear to rise slightly northeast or southeast, with setting points varying as well. It is not typical for the Moon to rise in the west; if observed, it could be an illusion, a misunderstanding of the time of observation, or a rare perspective due to Earth's rotation and the Moon's orbital movement.

If there are reports or perceptions of the Moon rising in the west, they might be related to timing (such as seeing the Moon setting in the west during sunrise) or location-based horizon tilt effects, but the fundamental rising direction remains eastward due to Earth's rotation.

In summary, the Moon rising in the west tonight is highly unlikely according to established astronomy and is probably a mistaken observation or misunderstanding of timing or perspective effects.
