This page provides links to maps of various soil and water related parameters, which can be used to determine areas affected by drought and how drought conditions may be changing from week to week or month to month. The results were obtained using the water and energy balance model GOES-PRWEB.

ARCHIVED soil and water-related maps and data:
Weekly rainfall, rainfall deficit and negative rainfall deficit (excess rainfall not shown) and effective crop coefficient
Soil Moisture Saturation
Volumetric Soil Moisture Content
Crop Stress Coefficient
Reference (Potential) Evapotranspiration
Natural Log of the Bowen Ratio
See current Drought Monitor Map for Puerto Rico
The following map shows the rainfall deficit (negative values) and rainfall excess (positive values).
The following map shows only negative values of rainfall deficit (areas of excess rainfall are not shown, i.e., white areas).
Crop Stress Coefficient: 1=No Stress, 0=Extreme Stress
