The low pressure area known as "System 90L" in the Eastern Atlantic Ocean is no longer suspect for tropical or subtropical development. On Sunday, December 8, System 90L's showers had diminished. The low was non-tropical and was located about 100 mile south of the central Azores Islands. Since then, upper-level winds have become hostile and the low pressure area has no chance of becoming tropical or subtropical. On December 8, NOAA's GOES East satellite captured a visible image of the low pressure area and at that time the circulation was even difficult to identify. By December 9, System 90L fizzled.
