Here is the weather forecast for Haiti, Port-au-Prince and other cities in the country.
According to the Haiti Hydrometeorological Unit (UHM), the air mass remains very humid and unstable over the center of the Greater Antilles. This situation is caused by a trough in the different levels of the atmosphere, located to the West-North-West of the island of Haiti, as well as a low pressure area located over the Caribbean Sea. Moderate to heavy rainy activities, accompanied by gusts of wind, are therefore expected during the day and evening. The departments most exposed to this bad weather system are Grande Anse, Nippes, Center, South, South-East and North-West.
Weather forecast for Haiti
The country will be very cloudy, with showers in the South and Grande Anse this morning. A slight feeling of heat is to be expected during the day, followed by calming in the evening. Maximum temperatures will range between 28 and 32 degrees Celsius, while minimum temperatures will range between 20 and 24 degrees Celsius. The sky will be cloudy to overcast at the end of the day and in the evening. Moderate to heavy rainy stormy activities, accompanied by gusty winds, are also expected, particularly in Grande Anse, the South, the South-East, Nippes and the North-West.
Concerning the flood warning, the UHM announces that the rains linked to this bad weather system could cause water overflows, flooding and landslides in the late afternoon and evening, particularly on the departments of Grande Anse, South, South-East, Nippes and North-West. The population of these departments is therefore asked to mobilize and respect all the usual safety instructions in the event of heavy rain.
Forecast for Thursday, November 28
L’UHM specifies that the trough of the different levels of the atmosphere will continue to influence weather conditions. Stormy showers, more widespread across the country, are expected, particularly in the great South and the Artibonite in the afternoon and evening. There is also an increased risk of flash flooding, especially on Grande Anse and the South, late in the day and in the evening.
Forecast for Port-au-Prince and surrounding areas
The sky will be very cloudy and windy during the day, with a slight feeling of heat. Temperatures will be rather mild in the evening. The maximum temperature will reach 31°C, while the minimum will be 23°C. The sky will become cloudy to overcast in the evening, and risks of thunderstorms are expected at the end of the day and in the evening.

How can communities in Haiti prepare for severe weather events like heavy rainfall and flooding?
Time.news Editor (TNE): Good day, everyone! Today, we have the privilege of speaking with Dr. Elaine Simon, a meteorologist specializing in tropical weather systems and their impacts, particularly in the Caribbean region. Thank you for joining us, Dr. Simon.
Dr. Elaine Simon (DES): Thank you for having me! It’s a pleasure to be here.
TNE: Let’s dive right in. The Haiti Hydrometeorological Unit has recently issued warnings about unstable weather conditions over Haiti. Can you explain to our audience what a trough is and how it influences weather patterns, especially in areas like Haiti?
DES: Absolutely! A trough is essentially an elongated area of low pressure in the atmosphere. In the case of Haiti, the trough to the West-North-West is leading to increased humidity and instability in the air mass over the Greater Antilles. This can amplify storm activities, causing moderate to heavy rain, as we are seeing today.
TNE: That makes sense. The forecast indicates a high probability of heavy rain and potential flooding. What specific factors make certain departments, like Grande Anse and Nippes, more vulnerable to these rainstorms?
DES: Great question! The geography of these regions plays a significant role. Areas with higher elevations and steep slopes, such as parts of Grande Anse, are particularly susceptible to landslides during heavy rainfall. Furthermore, urban areas with inadequate drainage systems can lead to rapid flooding. Given the intense, concentrated nature of the rain expected, these regions are on high alert.
TNE: Speaking of alerts, the UHM warned about possible flooding and landslides later in the day. How does a meteorological unit prepare local communities for such events?
DES: Meteorological units typically distribute advisories and alerts through multiple channels, including local media, social platforms, and community forums. They emphasize the importance of readiness, such as knowing evacuation routes and having emergency kits prepared. Additionally, collaborating with local government helps facilitate community awareness and disaster response plans.
TNE: That proactive approach is crucial. Can you elaborate more on the conditions that lead to such heavy rainfall? What meteorological signs do we look for?
DES: Certainly! Heavy rainfall usually corresponds with a combination of atmospheric disturbances, such as troughs or low-pressure systems, and prevailing moisture-laden winds. When these elements converge, they produce clouds that can lead to thunderstorms. Additionally, warm air can hold more moisture, contributing to intense precipitation. Therefore, when we see a rise in humidity levels along with these meteorological patterns, we’re likely seeing the precursor to heavy rainfall.
TNE: It’s fascinating how interconnected these systems are. What advice would you give to individuals living in affected areas to stay safe during such severe weather events?
DES: The priority should always be safety. If you’re in a flood-prone area, monitor updates through official channels, evacuate when advised, and avoid flooded roadways. Having a communication plan with family, keeping emergency kits stocked with essentials, and knowing the nearest shelter locations are all vital steps. Additionally, it’s wise to have sandbags ready if you’re at risk of flooding.
TNE: Fantastic advice, Dr. Simon. It’s essential for the public to stay informed and prepared. As we wrap up, do you foresee any long-term impacts that this weather pattern might have on Haiti, especially given its ongoing challenges with infrastructure and resources?
DES: Unfortunately, the cumulative impact of heavy rainfall can exacerbate existing vulnerabilities. Flooding can damage infrastructure, devastate crops, and hinder critical supplies of food and water. This can lead to prolonged economic and social challenges in communities already facing instability. Building resilient infrastructure and enhancing community preparedness are crucial steps for mitigating these impacts in the future.
TNE: Thank you for sharing your insights with us today, Dr. Simon. It’s been enlightening discussing these weather patterns and their implications for Haiti.
DES: Thank you for the opportunity! I hope the information helps your viewers stay safe and informed.
TNE: And thank you to our audience for tuning in. Stay safe and stay informed!
