More drought quenching rainfall fell today across Antigua yesterday December 16. A near stationary front (shown below on the surface chart) showered the island with much needed water. At the V. C. Bird International Airport (VCBIA), 10.9 mm of rain was measured, all falling between 2:45 pm and 6:45 pm. However, estimates from weather radar (shown below) indicate that as much as 50 mm may have fallen on northern side of the island. Over in Barbuda, a drenching 150 mm or more fell according to radar estimates. Going by what was actually measured by raingauge, at the VCBIA, the rainfall total now stands at 69.7 mm (2.74 in). This means that the Airport, thus far, has received near normal rainfall for December. However, above normal rainfall, above 91.4 mm (3.6 in) is forecast for the month. Thus, further quenching of the drought is anticipated.

The front did not just affect Antigua; satellite photo and TRMM data below show the cloud and rainfall signature patterns of the system stretching across much of the northern Caribbean from the Leeward Islands west to Jamaica and parts of Cuba.

Here are the rainfall totals reported by some of the other affected islands:

  • Robert L. Bradshaw International Airport, St. Kitts – 39 mm
  • Luis Muñoz Marín International Airport, Puerto Rico – 101 mm
  • Sangster International Airport, Jamaica – 38 mm

Rainfall at the VCBIA continues to run above normal for December. Exceeding 100 mm is a real possibility. If this were to happen, it would be the fourth time in the last five years. Continue to think rain.
