Reports from Ham Radio Operators:<br />

One Ham Radio Operator in Stony Hill,<br />

St. Andrew reported maximum<br />

sustained wind speeds <strong>of</strong> 120 km/h or<br />

75 mph <strong>and</strong> a corresponding<br />

atmospheric pressure <strong>of</strong> 992 millibars at<br />

2219 UTC (1719 hours local time) on<br />

Sunday August 19. Ano<strong>the</strong>r operator in<br />

Portmore, St. Ca<strong>the</strong>rine reported<br />

maximum sustained wind speeds <strong>of</strong> 158<br />

km/h or 98 mph at about 2030 UTC<br />

(1530 hours local time), while a third<br />

operator in Munro, St. Elizabeth<br />

reported sustained wind speed <strong>of</strong> 165 km/h or 103 mph between 0000 <strong>and</strong> 0030 UTC on <strong>the</strong> 20th<br />

(1900 <strong>and</strong> 1930 hours local time Sunday August 19) before <strong>the</strong> instrument broke. Wind speeds<br />

reported in Portmore <strong>and</strong> Munro indicated Category 2 hurricane force winds, while those<br />

reported in Stony Hill were category 1 hurricane force winds. These seem to be consistent with<br />

<strong>the</strong> swath <strong>of</strong> <strong>the</strong> wind data from <strong>the</strong> National Hurricane Centre (see figure 1.5) indicating that<br />

Jamaica should have experienced hurricane force winds.<br />

Rainfall<br />

Most <strong>of</strong> <strong>the</strong> rain gauges along <strong>the</strong> south coast <strong>of</strong> <strong>the</strong> isl<strong>and</strong> were ei<strong>the</strong>r washed away or blown<br />

away. As a result, just a few stations were able to report rainfall (Appendix 3). Of those stations<br />

able to report rainfall, Ingleside in Manchester reported <strong>the</strong> maximum 24 hour rainfall <strong>of</strong> 342.9<br />

mm. This was followed by amounts <strong>of</strong> 256 mm recorded at <strong>the</strong> Sugar Industry Research<br />

Institute (S.I.R.I.) station also in Manchester. This amount represents 183 % <strong>of</strong> <strong>the</strong> normal<br />

rainfall expected for that station for <strong>the</strong> month <strong>of</strong> August. In St. Thomas, <strong>the</strong> amount <strong>of</strong> rainfall<br />

recorded over <strong>the</strong> 2-day period August 19 <strong>and</strong> 20 for Morant Bay was 331.5 mm or 217% <strong>of</strong> <strong>the</strong><br />

normal expected for that station for <strong>the</strong> month <strong>of</strong> August. Norris also in St. Thomas followed<br />

with 24 hour rainfall amounts <strong>of</strong> 210 mm on <strong>the</strong> 19th. In St. Ca<strong>the</strong>rine, <strong>the</strong> two Bernard lodge<br />

stations (Blair Pen 251% <strong>and</strong> Phoenix Park 211%) reported in excess <strong>of</strong> 200% <strong>of</strong> normal rainfall<br />
