A newly formed tropical disturbance caused drought-busting,\u00a0Lenny-type<\/a>\u00a0rainfall across parts of Antigua. The system dumped over\u00a0270 mm<\/strong>\u00a0(close to 11 inches) across parts of the country, over the last 24 hours.<\/p>\n

\"\"<\/a><\/figure>\n

Of course, with this extreme rainfall, there was massive flooding in some areas. The impact is unfolding with images of almost submerged and abandoned vehicles, flooded businesses and homes and damaged roads.<\/p>

Last Night: Flooding at Woods, St. John\u2019s, Antigua<\/figcaption><\/figure>\n

Today: Same area as above (Woods, St. John\u2019s, Antigua) but after the runoff.<\/figcaption><\/figure>\n

This rainfall event was quite extreme, if not in amount, certainly with respect to intensity. In 24 hours, twice the month\u2019s total rainfall fell \u2013 twice November\u2019s average in less than 24 hours, in some places. The islands average rainfall for November is 149.4 mm (5.88 inches).<\/p>

The maximum 6-hour rainfall was higher than the average for most months. We measured up to\u00a0156 mm<\/strong>\u00a0(6.14 inches) in six-hours. This is more rainfall than we would have had from most tropical cyclones that have impacted the island. The max six-hour rainfall on record at the Airport is 175.2 mm (6.90 inches); the max for November for the same location is 158.7 mm (6.25 inches).<\/p>\n

In an hour yesterday, we measured peak rainfall total of\u00a097 mm<\/strong>\u00a0(3.82 inches), at the University of the West Indies \u2013 Five Islands Campus. At the Airport, the\u00a0record of 56.4 mm (2.22 inches) was broken by the 77.9 mm (3.07 inches)<\/strong>\u00a0measured between 4 and 5 pm, yesterday.<\/p>

\"\"<\/a><\/div>\n

Drilling down even deeper, there were occasions when the ten-minute rainfall total reached close to\u00a025 mm<\/strong>\u00a0(1 inch). This is almost unimaginable to think that in a space of 10 minutes, some areas would have had nearly an inch of rainfall.<\/p>\n

Putting the rainfall total into further perspective, the one-day total, for some areas, for this event is higher than the one-day total from Lenny recorded at the Airport. Lenny\u2019s maximum one-day total was\u00a0241 mm<\/strong>\u00a0(9.49 inches), at the Airport, as compared to over 270 mm (over 10 inches) from this event, at Five islands.<\/p>

\"\"<\/a><\/div>\n

More rain is in the forecast with another\u00a0100 to 200 mm<\/strong>\u00a0(4 to 8 inches) possible in the next 72 hours. This means more moderate to major flooding is likely.<\/p>
