Latest model guidance have Sanvu weakening as it slowly approaches the southern Marianas, dissipating as a significant tropical cyclone well east of the islands. However, as the tropical storm moves westward, it is likely to encounter less upper-level wind shear. This, along with a compact and near-stationary storm, indicates this system could hold its intensity a bit longer, allowing it to possibly move through the Marianas as a depression, increasing the expected rainfall amounts across the islands early to mid-week next week.
Although weakening for Sanvu is likely, the community is reminded the situation can change quickly and is advised to:
· Stay up to date with the latest information through the weekend;
· Be prepared to take action, if warranted, if the potential for heavy rain and gusty winds increases;
· Be alert for potential advisories for hazardous seas and small craft
