A flash-flood watch is in effect for SVG as of 6pm today, 22nd August 2021 and would remain in effect until 6pm Monday 23rd August 2021. Residents and motorists in areas prone to flooding and landslides or near rivers and streams should exercise extreme caution. Model guidance suggests showers could linger into Tuesday and Wednesday as the atmosphere is expected to remain moist.
