High Quality Content by WIKIPEDIA articles! Hurricane Julia was the easternmost Category 4 hurricane recorded in the Atlantic basin since reliable satellite observations became available. The twelfth tropical cyclone, fifth hurricane and fourth major hurricane of the 2010 Atlantic hurricane season, Julia rapidly developed on September 12 from a tropical wave near Cape Verde. Passing near the islands, the system quickly organized into Tropical Storm Julia the next day. On September 14, Julia attained hurricane status and subsequently entered a trend of rapid intensification; the storm strengthened from a minimal hurricane to a low-end Category 4 in only 24 hours. After peaking in intensity, further development was impeded as interaction with nearby Hurricane Igor began to occur; the storm was downgraded to a tropical storm by September 18. It subsequently moved into a region of unfavorable conditions, heading toward lower sea surface temperatures. Correspondingly, Julia entered an extratropical transition on September 20, and advisories on the storm were discontinued by that time.
