SYNOPSIS:
As the forecast period progresses, a surge of moisture and instability associated with an approaching strong tropical wave will result in deteriorating weather conditions. Expect an increase in showers and thunderstorms, some of which may be heavy at times. These conditions are likely to persist into Wednesday. Residents in low-lying and flood-prone areas are urged to remain vigilant and take necessary precautions, as localized flooding may become possible.
Sea conditions are expected to remain slight over the next few days.
STATE OF THE SEA: Slight WAVES/SWELLS: 2 to 4 feet
SPECIAL FEATURES:
- A tropical wave in the central tropical Atlantic has a low to medium (20–70%) chance of development over the next 2–7 days. Environmental conditions are expected to become more favourable by tomorrow, with a tropical depression likely to form by mid to late week.
- Another tropical wave, located about 400 miles east of the region, also has a low to medium (10–40%) chance of development within the next 2–7 days. This system could develop into a tropical depression later this week and is expected to bring showers and thunderstorms across the local area from Tuesday into Wednesday.
The Meteorological Department of Maarten will continue to monitor the Atlantic and provide updates accordingly.
OUTLOOK through Wednesday midday: Generally cloudy with scattered showers and thunderstorms.
