In heavy overflow and has been for several minutes since I showed up. Some convection over the vent. By 1302, it had dropped below overflow. Back in light overflow at 1306. Back below overflow at 1312. Overflow again at 1317. Still in light overflow since grand started at 1319. Runoff is heavy again at 1327. Never stopped overflowing when it got weaker. Middle of pool is surging up and down at 1329. Bubbling as well. It seemed to be slowly building as grand was erupting. Grand has now stopped. Still pulsing and gently boiling with good overflow at 1336. Pulsing and boiling rather suddenly stopped at 1338. Still in very light overflow at 1344. |
