As high heat, low humidity, dry vegetation and onshore winds threaten the Southland this week, causing the National Weather Service (NWS) to issue a red flag warning for a high risk of wildfire, especially in Antelope Valley and the San Gabriel Mountains, the service also issued warnings for several coastal areas, including Long Beach.

A Hazardous Weather Outlook has been issued today for Long Beach and Southwestern California for Wednesday through Monday, with dense fog expected to create both driving and boating hazards near the coast, according to the NWS.

Long Beach was also pinpointed within a Small Craft Advisory area today, which warns inexperienced mariners and those manning smaller vessels of hazardous sea conditions. Long Beach was also located just outside of a Beach Hazards Statement, which is issued by the NWS when threats such as strong rip currents, high surf and tidal overflow are possible.

The NWS forecast sunny skies today and highs of 78 in Avalon, LAX and 88 in Long Beach.

Temperatures are expected to fall slightly in some communities Wednesday, remain the same in others, then fall again on Thursday, after which they will remain at approximately the same level at least through Monday, according to the announcement.
