In November 2003 the islands experienced record breaking rainfall. St. Thomas experienced 18.39 inches of rain and St. John 18.91 inches. St. Croixâs highest rainfall was in September 1979 with an amazing 21.39 inches. Droughts are a larger problem because the islands are dependent on rain as a source of water.ainy months does not mean that there is continuous rainfall every day all month long, in fact most daily rainfall reports are below .10 inches. Rain showers are often short and typically occur early in the morning or at night. On a truly rainy day, it will rain off and on for the entire day.

Certain types of cysts occur in locations within the body that are not able to be seen by the naked eye. Internal cysts may not display any symptoms and will, therefore, go unnoticed until some type of imaging scan is completed. One such type in this category is a subchondral cyst.These form in spaces within the joints; spaces that are normally occupied by cartilage to cushion the bone end from another adjoining bone. Formation of these cysts is caused when that cartilage begins to wear away and the conflict of bone on bone occurs.Causes for the development of the cyst. These sacs that grow in the subchondral layer of bone just beneath the cartilage are most often the result of a degenerative disease called osteoarthritis.here are many common forms of cysts, but many people have no information on one called a subchondral cyst. This may be because they are not easily diagnosed without the benefit of a bone scan since this type of cyst occurs in the joints of bone.
