Pacific Tropical Outlook for Central America
Valid: Wednesday, August 19, 2026

There are no active hurricanes or tropical storms threatening the Pacific coast of Central America tomorrow. The only active tropical systems in the Pacific basin are located thousands of miles away near Hawaii and are moving westward, away from the continent.

Tomorrowâ€Ös weather along the Pacific littoral will be shaped by a sharp geographic split: severe late-afternoon convective thunderstorms in the south (Panama and Costa Rica) due to the Intertropical Convergence Zone (ITCZ), and an intense meteorological drought and heatwave in the north (El Salvador, Guatemala, and Honduras) driven by El Niño.

 Regional High-Impact Forecast

               NORTHERN PACIFIC LITTORAL             SOUTHERN PACIFIC LITTORAL
               (Guatemala, El Salvador)                (Costa Rica, Panama)
              ---------------------------           --------------------------- 

             | • Severe Heat (38-42°C)   |         | • Intense Convective Storms|
             | • Active Drought Blockade |         | • Rapid Flash Flood Risk  |
             | • Violent 80km/h Microburst|        | • Lightning & Urban Floods|
              ---------------------------           --------------------------- 

1. Southern Pacific Slope: Panama & Costa Rica (Severe Thunderstorms)
The Intertropical Convergence Zone (ITCZ) will sit directly along the southern Pacific coastline, trapping immense marine moisture.

    The Forecast: High humidity will make the morning feel suffocating, with actual temperatures reaching 31°C to 34°C and heat indices pushing 40°C.
    Hazards: Between 2:00 PM and 7:00 PM, intense solar heating will detonate widespread, heavy tropical downpours and frequent cloud-to-ground lightning. Localized urban flooding and sudden rises in rapid-response rivers are expected, particularly in Chiriquí and Veraguas (Panama), as well as the Central and South Pacific zones (Costa Rica).

2. Northern Pacific Slope: El Salvador & Guatemala (Heatwave & Drought)
Strong high-pressure systems and downsloping winds enhanced by El Niño will act as an atmospheric shield, ripping apart organized rain systems.

    The Forecast: Extreme, dangerous heat will peak tomorrow. The Ministry of Environment (MARN) in El Salvador warns of maximum temperatures hitting 38°C to 42°C in coastal plains and eastern valleys. Guatemala's INSIVUMEH confirms a persistent 25«ainfall deficit for the week.
    Hazards: While most of the day will be bone-dry, the extreme thermal energy accumulated by late afternoon will trigger isolated but highly violent convective cells along the volcanic chain. These localized storms will last less than an hour but are capable of producing destructive 80 km/h (50 mph) microburst winds, sudden downbursts, and falling trees.

 Marine, Surf, and Tidal Conditions

    Sea State: Moderate and safe for commercial shipping, with open-ocean significant wave heights averaging 1.0 to 1.5 meters (3 to 5 feet), primarily driven by long-period southwest swells.
    Coastal Hazards: Extreme caution is advised near river mouths during the late afternoon, as heavy inland storm runoff will collide with local tides, creating turbulent currents.

If you are planning marine navigation, fishing, or coastal transport tomorrow, let me know your exact coastal province or port, and I can pull the precise high-tide schedules for your sector.
