A massive cyclone is about to dump historic levels of rain on the Arabian Peninsula

A storm in the Arabian Sea is headed toward the deserts of Yemen and Oman on the Arabian Peninsula, bringing historic levels of rain to the region. 

Cyclone Chapala intensified from a tropical storm to a hurricane with 150-mph winds (making it a Category 4 storm on the five-category Saffir-Simpson Scale) in just 24 hours, The Weather Channel reports.

Here's what the storm looked like on Thursday as the storm started picking up steam. Chapala is expected to become a Category 5 storm before it makes landfall. Some estimates expect at least a year's worth of rain (on average the area gets about 4 inches) as a result of this single storm.

Chapala is expected to make landfall in Yemen and southwest Oman on Monday. Cyclones typically die down before making landfall, and in this case experts estimate that Chapala will dissipate as it approaches the arid desert.

This storm is being called a cyclone rather than a hurricane or typhoon because of its location. Storms of this kind that happen in the Indian Ocean (where the Arabian Sea is) are called cyclones; they're called hurricanes in the Atlantic and Northeast Pacific and typhoons in the Northwest Pacific.

Chapala is one of the strongest storms ever to form in the Arabian Sea, after Cyclone Gonu, which reached winds of 165 mph.

Here's the storm's trajectory, as of Friday, according to the Joint Typhoon Warning Center:

For a hurricane, cyclone, or typhoon to form, there must be some type of preexisting weather disturbance, the presence of warm tropical oceans, plus moisture and some light wind. If these conditions stick around for long enough, they can combine to produce these storms.

It looks like the storm is picking up some dust along the way as it approaches the Arabian Peninsula, which may help it slow down.
