Manual Updates
Use the admin page to manually trigger forecast updates:
- Go to Weather Verbose in WordPress admin
- Click Download & Parse Forecasts Now
- Check the status section to verify updates
Troubleshooting
Alerts Not Appearing
- Check if alerts exist: View the raw forecast files in
/wp-content/wx/
- Verify parsing: Check that
alerts_marine.php contains data
- Manual update: Trigger a manual forecast download
- Check shortcode: Ensure using correct shortcode (e.g.,
⛵⚠️
ADVISORY: SMALL CRAFT ADVISORY IN EFFECT THROUGH SUNDAY MORNING
not ⛈️
WARNING: WINTER STORM WARNING REMAINS IN EFFECT UNTIL 10 AM EST SUNDAY
for marine warnings)
Example Alert Detection
The parser looks for lines like:
...GALE WARNING IN EFFECT THROUGH LATE TONIGHT...
...SMALL CRAFT ADVISORY UNTIL 8 PM EST...
...WINTER STORM WATCH FROM FRIDAY EVENING...
Cache Issues
If forecasts seem outdated:
- Delete files in
/wp-content/wx/
- Trigger manual update from admin page
- Check file timestamps in admin page
Technical Details
Update Schedule
- Automatic: Every hour via WordPress cron
- Manual: Admin page button
- Cron job: Can be triggered via
wp-cron.php
Alert Detection Logic
The parser:
- Identifies alert lines (starting with
...)
- Extracts alert text
- Categorizes by type (WARNING, WATCH, ADVISORY)
- Assigns severity level
- Adds appropriate emoji
- Stores separately from forecasts
Performance
- File-based caching: No database queries
- Efficient parsing: Regex-based extraction
- Smart updates: Only downloads when scheduled
- Minimal overhead: Cached PHP arrays
Support
For issues or questions:
- Check
/wp-content/debug.log for errors
- Verify NOAA URLs are accessible
- Ensure
/wp-content/wx/ is writable
