Issued 3:39 PM PDT 16 August 2025
Conditions are favourable for the development of waterspouts.
Wind speeds inside the spray ring of a waterspout are 45 knots or higher. Vulnerable vessels are at risk of damage or capsizing. Keep in mind that waterspouts cannot be seen at night and may strike suddenly. Waterspouts are generally isolated in nature although they can also occur in families of two or more. Waterspouts are generally short-lived in nature, typically lasting 20 minutes or less.
