The Urban & Small Stream Flood Advisory will expire at 330 PM ChST this afternoon for the entire island of Guam. As the cloud tops are warming and rain cells stratifying, rain intensity and coverage has decreased enough for Urban and small stream flooding to no longer pose a threat at this time. More cells incoming may potentially bring further nuisance flooding later in the afternoon, so Flood Advisories may be re-issued, if conditions warrant. && LAT...LON 1327 14464 1334 14461 1340 14463 1344 14460 1346 14460 1348 14462 1350 14475 1352 14476 1354 14478 1366 14483 1368 14485 1368 14487 1363 14492 1362 14497 1361 14497 1359 14498 1351 14494 1341 14480 1326 14478 1322 14474 1322 14469 1321 14465 1324 14462 $$ EM
