Long Beach, at the southern edge of the Los Angeles metro area, has a Mediterranean climate with around 300 mm (about 12 inches) of rain a year, concentrated almost entirely in the winter months with a long, dry summer. As a major port city, sudden winter storms, particularly atmospheric river events that can bring intense rainfall in a short period, have real operational significance for shipping traffic in addition to the flash-flooding and mudslide risk they pose to the surrounding hillside communities. Because a typical summer week here involves no rain at all, radar is most useful during the concentrated winter storm season. NWS Doppler radar KVTX (Los Angeles/Oxnard) covers the region.
