Unsecured items could blow around. .Marine Conditions...Hazardous conditions for small craft in areas with seas of 7 feet or higher, particularly across the offshore Atlantic waters, coastal waters of northern and northwestern Puerto Rico and Mona Passage.. Small craft should exercise caution elsewhere across the local waters. .Rip Currents...Life-threatening rip currents are likely in the surf zone, particularly across northern Puerto Rico, from Rincon and Aguada to Fajardo, and Culebra.. These life- threatening conditions are possible across southwestern Puerto Rico and Viques, with isolated stronger rip currents possible elsewhere, especially near piers, jetties and channels. .DAYS TWO THROUGH SEVEN...Tuesday through Sunday Moderate to locally fresh winds and a weak northerly swell will continue to produce hazardous marine conditions through Tuesday, with a high risk of life-threatening rip currents persisting. By the end of the workweek, warmer temperatures are expected to return, driven by southeasterly winds. Starting late in the week and continuing into the weekend, a significant surge in moisture, coupled with favorable upper-level conditions, will enhance shower and thunderstorm development, increasing the risk of flooding and the potential for lightning activity and gusty conditions. .SPOTTER INFORMATION STATEMENT... Spotter activation will not be needed. $$
