ESFSJU The active afternoons experienced in the past couple of days have maintained saturated soils along a great portion of the interior and west of Puerto Rico. These rains have also recharged must of the stream channels in Puerto Rico, with the exceptions of a few river in the eastern-interior and southeast. The forecast for this week calls for a low level disturbance moving in today, and a tropical wave coupled with an upper level low arriving on Wednesday and Thursday. With the disturbance reaching the islands today, the best chances of heavy showers and thunderstorms are early for the Virgin Islands, and then this activity will spread into Puerto Rico, reaching the east, the San Juan metro area, the interior and west. The wave moving in on Wednesday and Thursday looks stronger, and will likely cause an increase in the coverage of showers and thunderstorms in Puerto Rico and the Virgin Islands. So far, the event is not expected to be a complete wash out, but the local guidance are hinting on an upper and low level atmospheric pattern favorable for rainfall production. The main threats in Puerto Rico for most of the workweek will be the risk of urban and isolated flash flooding, landslides, water surges along rivers, and some rivers reaching flood stage. Rainfall accumulation could range from 1-2 inches each day, with higher isolated amounts, especially on Wednesday and Thursday. The main threats in the Virgin Islands are water surges along drainage guts, ponding of water in roadways and low-lying areas, and isolated urban flood and landslides. Rainfall accumulation could range from up to an inch each day, and very isolated higher amounts. The users should continue to monitor the evolution of the forecast, and stay tuned for any flood products issued by the National Weather Service. This product will be updated again only if conditions change.
