Des pluies supérieures à la moyenne ont été observées sur une grande partie d'Haïti au cours des 30 derniers jours, après des pluies moyennes à inférieures à la moyenne en mars, et des crues soudaines ont été signalées à la mi-avril. Des pluies moyennes étaient prévues pour mai. Le moniteur suit la saison en cours : cumuls pluviométriques rapportés à la moyenne de long terme, état de la végétation à partir du NDVI satellitaire, et ce que les deux impliquent pour les semis, le développement des cultures et la récolte. La date de couverture clôt la fenêtre de 30 jours couverte.

FORECASTS SUGGEST INCREASED PRECIPITATION
IN MAY
During the month of March, average to below-average
rainfall was recorded across most of Haiti. Deficient rainfall
was observed during the first 12 days of April, but an
abnormally strong increase in rainfall caused flash floods in
localized areas, and changed conditions from dry to wet
across most of the country (Figure 1). However, several
consecutive days of below-average precipitation have been
observed in the last week.

Figure 2. NMME probabilistic forecast for May 2025.
CMORPH hydro estimator records show that in Les Cayes,
rainfall totals on April 13 and 14, exceeded 60 millimeters.
Liancourt recorded nearly 60 millimeters of rain on April 16.
These areas were among the most affected by significant
accumulations of rainfall in a short period. The rest of the
island also recorded above-average rainfall, but with values
that did not exceed 20 millimeters, which contributed to the
normal development of the Printemps season crops. NDVI
values indicate average to above-average vegetation
conditions, except for some localized areas affected by flash
floods.
Forecasts show that May rainfall is likely to be average,
favoring the development of crops (Figure 2). Rainfall
forecasts for the next two weeks indicate an average
performance, however, erratic rainfall is likely to persist in the first week of May.
