The National Weather Service (SNM) in San Juan forecasts above-normal temperatures in Puerto Rico through the weekend, particularly in coastal, low-lying, and urban areas. ^[1][2] The SNM warned that excessive heat will remain the primary meteorological risk, particularly for vulnerable populations and those without adequate cooling systems. ^[3] Meteorologists advise frequent hydration, reducing sun exposure, and avoiding leaving children or pets in vehicles during the heatwave. ^[4] The SNM recommended staying hydrated and avoiding outdoor activities during peak daytime heat. ^[5] The SNM warned of a moderate risk of dangerous marine currents affecting most local beaches until Sunday, with improved conditions expected by Monday. ^[6] On November 13, the SNM noted that reduced humidity and stronger winds could slightly lower perceived heat but might concentrate high temperatures in specific zones. ^[7] The SNM predicts mostly stable conditions through Sunday, with brief afternoon showers possible in southern and northwest regions. ^[8]
