The Dominican Republic's Emergency Operations Center (COE) has placed 22 provinces plus the National District under a green alert as a weather trough brings days of moderate to heavy showers, thunderstorms and gusty winds to much of the country. The main concerns are urban flooding and rising water in rivers, streams and ravines, with conditions expected to intensify from Thursday.

The alert covers a huge slice of the map — including tourist-heavy spots like Punta Cana (La Altagracia), Puerto Plata, La Romana, Santiago and Santo Domingo itself, along with San Cristóbal, La Vega, Barahona, San Pedro de Macorís, Pedernales, Azua, Peravia, Dajabón, Santiago Rodríguez, Valverde, Monte Cristi, Espaillat, Independencia, Bahoruco, San José de Ocoa and Monseñor Nouel. In other words, if you're holidaying in the DR this week, your area is probably on the list.

A green alert is the lowest rung on the Dominican warning scale. It doesn't mean evacuation — it's a heads-up to stay informed, review your household or hotel emergency plan, and be ready if conditions worsen. The COE's specific advice is worth following anywhere in the country: don't cross rivers, streams or ravines on foot or by vehicle, steer clear of flood-prone zones, and keep an eye on official weather updates. Emergencies go through the national 911 system, which operates nationwide.

For visitors, the practical impact is mostly inconvenience rather than danger: downpours can delay transfers, swamp streets in Santo Domingo and close excursion routes, especially in river valleys and along the coast. Resorts in Punta Cana and La Romana are well used to handling tropical weather, and hotel staff will usually brief guests if anything changes. If you've booked waterfall hikes, river tubing or trips into the Cordillera Central, expect operators to reschedule or cancel while water levels are high — that's standard practice, not overcaution.

The trough behind all this is a fairly common feature of Caribbean weather, and green alerts typically stand down within a few days once the system moves through. Still, it's a good reminder that the DR's rainy spells can be intense even when the sun is out between showers. Pack a light rain layer, keep electronics in dry bags for boat or beach days, and follow the COE and local civil defence accounts for updates in real time. If you're travelling solo into remoter areas like the Barahona or Pedernales coast, tell your accommodation where you're headed and avoid any route that involves crossing moving water.

Bottom line: no need to change your plans, but do build some flexibility into the next few days and take flood warnings seriously if you're driving yourself.
