Official weather monitoring and emergency response agencies across Central America have issued critical, active watches and warnings for tomorrow, Thursday, August 20, 2026. The istmo remains meteorologically split: the southern countries face high-risk flooding and saturated terrain from recent tropical waves, while parts of the northern Pacific coast continue under severe drought and heat protocols.
Costa Rica: Elevated Orange and Yellow Flood Alerts
The National Emergency Commission (CNE) and the National Meteorological Institute (IMN) maintain heightened alert states due to widespread flooding from consecutive tropical waves:
Orange Alert (High Risk/Heavy Rainfall): Enforced across the Northern Zone, the entire Caribbean slope, and the canton of Turrialba. Soils in these mountainous regions remain dangerously saturated at 85o 95meaning any incremental rainfall tomorrow will immediately trigger river overflows and landslides.
Yellow Alert (Moderate Risk): Active for the Valle Central, Central Pacific, and South Pacific regions. Civil protection teams have activated temporary shelters for evacuated families in flood-prone river basins.
Panama: Extended Countrywide Rain and Maritime Notices
The National Civil Protection Service (SINAPROC) and the Institute of Meteorology and Hydrology of Panama (IMHPA) have extended their security guidelines into tomorrow due to an active tropical wave footprint:
Aviso de Prevención (Significant Rainfall and Lightning): Effective countrywide, focusing heavily on Bocas del Toro, Colón, the Ngäbe-Buglé Comarca, and Chiriquí. Runoff from persistent afternoon downpours threatens sudden urban flooding and flash floods.
Hazardous Sea Advisory: Active for the entire Caribbean shoreline due to accelerated trade winds. Expect rough seas with chop and waves spiking up to 2.5 meters, significantly limiting artisanal and recreational navigation.
El Salvador: Extreme Heat and Soil Desiccation Watch
The Ministry of Environment and Natural Resources (MARN) continues to prioritize extreme dry events over the Pacific slope caused by El Niño:
Meteorological Drought Warning: Civil protection is closely tracking the impacts of the third major drought period of the year. Severe lack of rainfall across the eastern and central departments has created intense agricultural soil stress.
Heatwave Watch: Tomorrow will feature a dangerous thermal peak, with maximum temperatures holding between 38°C and 42°C in coastal plains and paracentral valleys. MARN warns against physical exertion during peak hours due to extreme UV radiation.

Guatemala: Prolonged Mid-Summer Canícula Notice
The National Institute of Seismology, Vulcanology, Meteorology, and Hydrology (INSIVUMEH) maintains its operational risk matrix for the southern basins:
Deficit Rainfall Warning: Active watch on the canícula (seasonal drought block), which is generating a 25eficit in expected rainfall for southwestern and eastern agricultural areas.
Hydrological Deficit Watch: Daily river bulletins remain active to monitor critically low water volume tables in major waterways feeding into the Pacific basin.
Critical Safety Recommendations for Tomorrow
In Southern Flood Zones (Costa Rica/Panama): Never attempt to cross flooded roads, swollen streams, or rapid-response rivers, whether on foot or in a vehicle.
In Northern Drought Zones (El Salvador/Guatemala): Practice rigorous hydration and sun protection. Be vigilant for brief, violent convective storms right at sunset, which can cause sudden microburst winds up to 80 km/h
