The Flash flood warning that was issued earlier has been downgraded to a Flash Flood Watch and is valid from 2pm until 8 pm this evening. This is due to a few light to moderate scattered showers possible this evening.
The upper level trough continues to move away from the islands to the NE out into the Atlantic ocean while the surface trough continues to move westward through the island chain. Due to this, some lingering moisture and instability may persist over the islands during the watch period. This will be reviewed and updated accordingly through out the watch period.
The Flash Flood watch that was in place has been upgraded to a Flash Flood Warning, effective immediately, up until 2pm this afternoon. Further reviews will be made at the said point in time.
Overnight an upper level low pressure system coupled with a surface trough affected the Leeward Island and thus created the instability over St. Kitts and Nevis. This resulted in some overnight thunderstorms and some showers which were moderate to heavy at times. The upper-level trough continues to move to northeast over the Atlantic and away from the Leewards and hence there would be a reduction in instability. However, conditions are expected to remain cloudy to overcast for most of the morning with a gradual improvement as the day progresses due to the effect of the surface trough. Therefore, a FLASH FLOOD WATCH is in effect for St. Kitts and Nevis until 2pm and this will be reviewed at that time to determine whether to extend it or discontinue it. Persons are asked to exercise caution when crossing the ghauts and waterways especially if they are flowing.
